refraction of a ray of light when it passes through a semicircular piece of acrylic. An initial hypothesis would suggest that as you increase the angle of incidence, the angle of refraction would also increase, but certainty not proportionally. During the physics lessons you learnt the relationship between the angle of incidence θi and the angle of refraction θr is given by Snell’s law, which states that Where n1 is the refractive index of the medium from where the ray of light enters

I am the Human Resource Manager assigned to hire new sales associates in the fiber optic division. Upon interviewing each candidate only one candidate stands apart from the rest. I considered Jake, but quickly disqualified him due to instability. Making a change from a career as an accountant to sales shows he is not willing to work for a company for the long run. He is new to sales and does not have prior knowledge of fiber optics. Lynn has good people skills and is a leading expert in the fiber

Questions A. How did the angle of incidence compare with the angle of reflection? B. In trial 5, you aimed the incident ray directly along the normal. Describe the path of the incident and reflected rays for this special case. C. Where might errors occur in this activity? D. How would these errors affect your conclusion? E. Billiards is a game that makes use of reflection (Figure 2). How could the results of this activity help you in such a game? F. What other sports or activities make use

focus light or simply distort the reflected image (“Mungan,” 1999). Geometrical optics, or ray optics, describes light propagation in terms of "rays". The "ray" in geometric optics is an abstraction, or "instrument", which can be used to approximately model how light will propagate. Geometrical optics provides rules, which may depend on the color (wavelength) of the ray, for propagating these rays through an optical system. This is a significant simplification of optics that fails to account

An Atlanta based Fortune 500 Company has recently hired you as a Human Resource Manager. You are in charge of hiring new sales consultants for the fiber optics division of this organization. Due to the competitive marketplace, sales and revenues are at an all-time low. During your interview, you stated that you could serve as a valuable asset to this company. You noted your long-standing history of selecting the best candidates for sales positions and stated that you could bring the sales division

living organism. The effect of radiation depends on the type of radiation and the period of exposure. Some of the effects include cancerous cells caused by the high dose of x-ray radiation that disrupts normal chemical processes of the body cells causing them to die or to grow abnormal. Also, excessive exposure of X-rays to pregnant women may result in severe outcomes like infant death, congenital abnormality and a far extent stillbirth. Consequently ionizing radiation is a potential hazard to the

------------------------------------------------- What is a Cosmological Constant? Einstein first proposed the cosmological constant (not to be confused with the Hubble Constant) usually symbolized by the greek letter "lambda" (), as a mathematical fix to the theory of general relativity. In its simplest form, general relativity predicted that the universe must either expand or contract. Einstein thought the universe was static, so he added this new term to stop the expansion. Friedmann, a Russian

detrimental effects to those who are exposed to its radiation. Radiation, in Physics, it is defined as the process of transmitting energy through space. There are two types of radiation exposure—82% is from natural resources such as cosmic and solar rays and 18% of the exposure is from man-made radiation. Radiation injures the body by destroying cells and parts of cells. It hinders cells from dividing which gives rise to cells which does not have the ability to reproduce.

the most important diagnostic tools available to doctors and has revolutionized the medical diagnosis of patients. The use of medical imaging has enabled doctors to see inside a patient without having to cut them open. Medical imaging, especially X-ray examinations and sonography which is also known to some as ultrasound, is essential in an everyday medical setting. Preventive medicine as well as healing medicine depends on the proper diagnosis and treatment by physicians, and the use of diagnostic

it was back in 1961. Computers were not household products back then. If you look in a house today you will see at least one computer in most homes. Not only were computers not household items but flat screen televisions, cable, internet, DVD/Blu-ray player, cell phones, digital cameras/camcorders were not in the homes either. With all these things it’s clear that we have more now than people did fifty years ago and these are only a few examples of what we have now that was not around fifty years
