Physics of sound Sound is a mechanical wave, sequence of waves is resulting from an air pressure disturbance produced by vibration, and sound propagates through the medium such as air or water. During the propagation, sound can be reflected or attenuated by the medium. Humans can hear the sound is because the vibration pass the wave in to our ear, this is called Traveling Longitudinal Waves. The propagation of the sound can be affected by the density and pressure. The temperature determines the

Quantum mechanics (QM – also known as quantum physics, or quantum theory) is a branch of physics dealing with physical phenomena where the action is on the order of the Planck constant. Quantum mechanics departs from classical mechanics primarily at the quantum realm of atomic and subatomic length scales. QM provides a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter. In advanced topics of quantum mechanics, some of these behaviors

Physics Essay January 20, 2010 Experiment vs. Observation -Experiment: an operation or procedure carried out under controlled conditions in order to discover an unknown effect or law, to test or establish a hypothesis, or to illustrate a known law -Observation: an act of recognizing and noting a fact or occurrence often involving measurement with instruments -Measurments: Needs units, cm, inches, degrees etc. Reasons for different units of measurements are 1) practical application and 2) cultural

INTRODUCTION A mirror is an object that reflects light or sound in a way that preserves much of its original quality prior to its contact with the mirror. Some mirrors also filter out some wavelengths, while preserving other wavelengths in the reflection. This is different from other light-reflecting objects that do not preserve much of the original wave signal other than color and diffuse reflected light. The most familiar type of mirror is the plane mirror, which has a flat surface

tests were done in the physics laboratory in central Italy, under the mountain of Gran Sasso, and conducted about 15,000 times all with the same results. The results were neutrinos arriving 60 billionths of a second earlier with an error margin of plus or minus 10 billionths of a second. They experimented for three years before making public this amazing discovery on September 22, 2011. To have a better understanding, one must first be familiar with some basics of physics. Neutrinos are electrically

Will Einstein's 1905 theory of relativity - one of the most fundamental pillars of physics - that underpins "nothing can travel faster than light-300,000 kms, or 186,000 miles, per second" be proved wrong? The speculations started coming after scientists at the world's largest physics lab CERN claim to have clocked sub-atomic particles or neutrinos travelling faster than the speed of light. European Organization for Nuclear Research CERN, near Geneva, says a neutrino beam shot off from a particle
