!!!What Is A Wave Period?

Have you ever tried surfing? In order to surf, we need waves. However, there are things that a surfer needs to consider when looking at waves. One of the things that surfers look at is the size of the wave. For more experienced surfers, they will most likely want to surf on waves with a high amplitude. Also, it won’t be any fun if a wave appears and disappears quickly. Surfers will want to ride waves that last long, or waves with a long cycle, and so they look at the wave period.

The __wave period__ tells us how long it takes for a wave to complete its cycle, or we can say that it is the time it takes for two wave peaks to occur. The conventional symbol for wave period is ‘’T’’, and its standard unit is in ‘’seconds’’. …show more content…
A quantity that is related to the wave period is the frequency of the wave. The __frequency__ is defined as the number of repeating cycles per second. If we look at the picture below, it shows us five different waves whose frequencies vary in a given period of time. The top wave (red), has the ‘’lowest frequency’’ among the five because it has the least number of repeating cycles, and the bottom wave (pink) has the ‘’highest frequency’’ because it has the highest number of repeating cycles.

How are frequency and period related? __Frequency__, and we will be using the symbol ‘’f’’, refers to the number of cycles that are completed in a certain amount of time, and can be obtained by dividing the velocity, ‘’v’’, by the wavelength (symbol: lambda). The unit of velocity is usually in m/s, and for wavelength, it is usually in meters. The unit of frequency is Hz (hertz), which means a cycle that repeats per second. The formula for frequency is:
Frequency=Velocity/Wavelength …show more content…
What are the wave periods for the two colors? Which color has a higher wave period?

Given: f (red)= 4 ×〖10〗^14 f (violet)= 8 ×〖10〗^14

Find: wave period (T):
T=1/f
Substitute the formula:
T (red)=1/f = 1/(4 ×〖10〗^14 )=2.5 × 〖10〗^(-15) s
T (violet)=1/f = 1/(8 ×〖10〗^14 )=1.25× 〖10〗^15 s
Final Answer:
The period for color red is T = 2.5 × 〖10〗^(-15) s
The period for color violet is T =1.25 × 〖10〗^(-15) s
The color with the higher wave period is the one with the lower frequency, which is color red

!!!Lesson Summary
Everyday, we encounter waves. Sometimes we see them when we go to the beach and look at the ocean. Other times, they are invisible such as the waves in microwaves and radio waves. Different waves have different frequencies and

...any existing computer security as easily as you unzip your fly. We’re entering an era of cyberwar, so imagine how power might shift if one country gets the ability to invade any other country’s computer systems while putting up the ultimate computer defenses. That’s a major reason nations are pouring money into this research. The U.K., China, Russia, Australia, Netherlands and other countries are in the game. In the U.S., the CIA, National Security Agency and Pentagon are all funding research, while Los Alamos National Laboratory operates one of the most significant quantum computer labs. Negotiations to keep nuclear weapons from Iran are certainly critical, but if you play out the promise of quantum computing, an American machine could bust into Iranian systems and shut down all that country’s nuclear activity in an instant. It’s like a game of rock-paper-scissors: Nukes might be the world’s version of a rock, but quantum computers would be paper, winning every time. And yet, quantum computing research isn’t self-contained and secretive in the manner of the Los Alamos atomic bomb work during World War II. Some of it is academic work at universities such as the Massachusetts Institute of Technology, with findings shared in scientific papers. Technology companies are working on this, too, since these things have the potential to be business nukes. IBM, Google and Microsoft all fund research. Imagine if Google gets one before Microsoft. That pesky Bing could wind up vaporized...

Rossby

...and Pioneer in Atmospheric Dynamics ABSTRACT Carl Gustaf Rossby, a Swedish born mathematical physicist and later meteorologist is among the greatest contributors to modern-day meteorology. It was through his extensive research in the general circulations, that modern day weather forecasting has emerged to what it has become today. Rossby had a well-established career in the geosciences, with a broad educational background. It wasn’t until later in his life did he come to publish his greatest works. Rossby published three works in the late 1930’s and early 1940’s that involve potential vorticity, which would help establish the ground work for his most famous work on Rossby waves. The 1936 paper shows the conservation of potential vorticity in a hydrostatic, shallow fluid state, while the 1938 paper is an extension to the highly stratified hydrostatic flow, this time using isentropic coordinates. The term potential vorticity is actually never used until the 1940 paper where it is introduced. The 1939 work by Rossby is considered by some the most famous work contributed by Rossby, as he explains the semipermanent centers of action which would become the well-known Rossby waves. INTRODUCTION When people think of meteorology, the first names to appear are John Dalton, Gabriel Fahrenheit, William Ferrel, and Anders Celsius. These men are the founders of modern meteorology and made tremendous contributions...

Native Americans

...diverse nation on the planet. There may be other facts disputing this assumption but the United States beats other culturally diverse nations in terms of the tolerance and harmony between the resident cultures. All this can been attested to the fact that America is an Immigration Country. The country constitutes people from different parts of the world. The process of people moving into the new world that is the Americas where the United State lies began centuries ago and has been an ongoing process to the current day. This paper examines the origins of their Native Americans. This paper also explores their journey into the Americas as the first Immigrants. Their settlement patterns and ways of life will also be examined. The paper also explores how the Native Americans in the Americas fared during the European conquest of the region that is currently identified as the America. Euro-Indian relations, conflicts and their aftermath is also a focus point of the paper, which culminates into the current state of affairs of the Native American community in the Americas. Origins of the Native Americans There are diverse sources of information on the origins and history of the Native Americans. They include oral history passed down through generations. This oral history is as diverse as the Indian Nations. Different tribes have different folklore to explain their origins. For instance, the Haida who reside in British Columbia say that man was shaken out of a clam shell by a raven. The...

Lorenzo in the Lige

...FINAL EXAM STUDENT’S MANE: LORENZO NICOLAS MBA OBAMA PROFFESOR’S NAME: NINA WALKER SCI110 STRAYER UNIVERISTY March 19, 2014 1. There are two types of weathering. The first is mechanical weathering, the gradual breakdown of rock to sand, and then to silt, or powdered rock, and finally to clay through physical means. Mechanical weathering occurs in a variety of ways. For example, Heat and cold may cause minerals within a rock to expand and shrink at different rates, creating cracks. Water may seep into those cracks and freeze, expanding and splitting the rock. A raging river or ocean waves can smash rocks against each other, wearing the outsides smooth and turning rocks into sand. Or sand carried by the wind can act like sandpaper, slowly wearing rock away. A Glacier can rub debris against the rock beneath it, also acting like sandpaper. Even plants can force rocks to split as roots creep into cracks and grow. The second type of weathering is chemical Weathering, the breakup of rock caused by a change in its chemical makeup. Rain is the most common producer of chemicals that can weather rock. For example, Rain absorbs carbon dioxide and sulfur dioxide from the atmosphere, forming carbonic acid and sulfuric acid, two liquids capable of dissolving other materials. The levels of carbonic and sulfuric acids in rain, while generally weak, can over time dissolve rock such as limestone, freeing other types of rock. Over very long periods, rain can even dissolve enough limestone...

Managing for the Future

...Virtual Management - a New Business Organization Paradigm JJ Murphy Negotiation Newsletter Calum Coburn Co Ltd ( private paper). This article discusses how traditional organizational management methods and structures are failing to adequately accommodate a complexity-based world view, which is characterized by discontinuous change, hyper competition and the exponential explosion of information science. Virtual organizational management is the needed change in the management paradigm. -------------------------------------------------------------------------------- This article argues that traditional management methods and structures are failing to adequately accommodate a complexity-based world view, which is characterized by discontinuous change, hyper competition and the exponential explosion of information science and shows how the management paradigm has been updated by the new era of the virtual structures. While the management structures and systems developed by such researchers as Weber, Fayol, Taylor and Drucker in the 19th and 20th centuries established a management paradigm which has endured up to the millennium, these "simple" structures and systems were more suited to a time when competition was slower, less aggressive, and characterized by long periods of stability, and when information science was in its embryonic or primordial stage. It is abundantly clear, however, that the arrival of the 21st Century demands a fundamental rethink, and the development of...

Extraterrestrial Life

...Astronomy Research and the Search for Extraterrestrial Life The objective of this paper is to discuss life here on Earth and the possibilities of extraterrestrial life in one’s solar system. The team will describe the properties of life on Earth and explain the theories for the genesis of life, including the theory of natural selection. Members will provide a brief description of the evolution of life and include a geological timescale that describes specific eras throughout the previous three billion plus years. The team will assess the possibilities of extraterrestrial life, and results will be presented. Describe the properties of life on Earth Properties of life on Earth are what define the word life. The properties of life consist of cells and reproduction, responses to the environment, growth and development, and evolution. Every living thing is collected through cells which make tissues and organs that make a living organism. All living organisms can produce such as humans, animals, bacteria, and plants called asexual reproduction. The responses of the living in the environment are through any changes occurring in “light, sound, heat, and chemical contact” through “eyes, ears, and taste buds” (Cliff’s notes, 2011, para. 3). Behavior is one way that all living organisms changes through the environment such as the food chain for one’s survival. Growth and development of an organism takes in all substantial amount of information through energy of building...

...1]Main articles: Statistical mechanics, thermal fluctuations, and statistical physics Albert Einstein's first paper[88] submitted in 1900 to Annalen der Physik was on capillary attraction. It was published in 1901 with the title "Folgerungen aus den Kapillarität Erscheinungen," which translates as "Conclusions from the capillarity phenomena". Two papers he published in 1902–1903 (thermodynamics) attempted to interpret atomicphenomena from a statistical point of view. These papers were the foundation for the 1905 paper on Brownian motion, which showed that Brownian movement can be construed as firm evidence that molecules exist. His research in 1903 and 1904 was mainly concerned with the effect of finite atomic size on diffusion phenomena.[88] General principles He articulated the principle of relativity. This was understood by Hermann Minkowski to be a generalization of rotational invariance from space to space-time. Other principles postulated by Einstein and later vindicated are the principle of equivalence and the principle of adiabatic invariance of the quantum number. 2] Main article: History of special relativity Einstein's "Zur Elektrodynamik bewegter Körper" ("On the Electrodynamics of Moving Bodies") was received on 30 June 1905 and published 26 September of that same year. It reconciles Maxwell's equations for electricity and magnetism with the laws of mechanics, by introducing major changes to mechanics close to the speed of light. This later became known as...

Rational Management

...Running Head: Management process, linear and nonlinear management, ordinary and extraordinary management, rational management, chaos theory Management - from rational management to chaos theory Submitted to Dr. D. Coleman By JJ de Klerk In partial fulfillment of the requirement for the Doctorate in Business Administration Swiss Management University March 3, 2012 1 1. Introduction Developments over the last few decades have led to a new way of thinking in economic and management approaches. The scientific approach to management, which emphasizes the basic management functions of planning, organizing, leadership and control, now seems unable to explain the era of change that characterizes economies and organizations alike. This paper will focus on explaining the rational management model, focusing on ordinary management, and go on to discuss the new approaches such as chaos theory – also called complexity theory - and the need for extraordinary management and innovation. 2. Rational management Management and organization science literature have until recently focused on the objective control of agents and worked on the assumption that interactions can be described in linear terms (Webb, 2005). When difficult decisions have to be made, many managers and strategists rely on the economics view in which profit maximization is the guiding principle. Executives will us the rational model tools described above, and believe that precise solutions should be achieved...

Also according to this study, the digital book and digital media in general should know a better situation and favorable growth in the coming years, most users remaining faithful to the paper (including books), seeing the new devices with only additional functions. In addition, unlike the music industry or the audiovisual industry, there are very few parallel market, where users can illegally download works. If this phenomenon were to grow, then it may be as difficult for the publishing industry as the entertainment industry. Currently, there are three main schools of thought on the so-called traditional print media and its evolution towards digital media. Some see through this trend the death of newspapers and even the journalists (the professional ones). We cannot give them completely wrong, when you look at recent news.

Ska Work Cited

...org/cgi/reprint/2003/87/183.pdf (Heathcott, 2003) The first wave of ska was the main focus of this article the first wave erupted in the early 1960s out of the energetic dance hall culture of urban Jamaica among working-class youth cobbling together old island traditions and new forms of expression from arrange of materials found in American, British, and Jamaican popular culture. I was introduced to the real definition of Rude Boy they said they were a suit and tie hooligan bent on turf protection and the defiance of adult authority. This matched what I had in mind when I thought of the rude boys I know today. I learned that many artists associated with the global reggae explosion of the 1970s, such as Bob Marley, Bunny Livingstone, Toots Hibbert, and Lee “Scratch” Perry, got their start as young Rude Boy instrumentalists in ska bands. By the late 1960s, Marley and other stars began to slow down the tempo of ska, launching experiments with the genre that would result in rocksteady and reggae music. Before reading this I had always thought that reggae and rocksteady came before the upbeat ska music was formed. This article gave me a lot of good information about the first wave of Ska and how Ska came to be in the first place. I never knew about a lot of the things that influenced the youth to come up with the music they did. I feel like after reading this article I got more then enough information to write a very good page about the first wave of ska for my website. Stambuli, N.S. (n.d...

The Developmment of Comm Theories

...THE DEVELOPMENT OF COMMUNICATION THEORIES: A Critique Paper Since the inception of communication as a discipline of knowledge, scholars have come up with many theories related to its components. In fact, the encyclopaedia of communication theories (Littlejohn, 2009) has identified more than 300 relevant theories, a testament that the field is already making a big wave in the academic arena. It has been a product of many minds converging into one vision – to enrich the communication field. However, it was not an easy road for these intellectual minds as they are confronted with issues that still need to be resolved. In this paper I will try to present first the rich beginning of communication theories and in light with this development context follows my presentation on the varied problems confronted the field of communication theories as well my personal views on the matter. Historical Beginning There are two insights into how communication theory came into being – the religious view and the philosophical aspect. Although most of communication theories book do not include the religious view, I find it necessary to take into account the dogmatic view to present the variations of its origin. The religious view is demonstrated in the Holy Bible especially in Genesis when God communicated with man and man had the ability to communicate with Him and with each other. It is no wonder then that other writers of Bible theorize about communication. Notably, the Old Testament portrays...
