Georgia State University: Hyper Physics: Behavior of Incident Light

The meaning and cause of refraction--as well as Snell's law of refraction--are discussed. Includes an interactive problem-solving form in which visitors relate angles of refraction to the incident angle and the indices of refraction.

This site from Georgia State University Physics Department defines kinetic energy and compares and contrasts it with other forms of energy. Provides an equation and links to further, more-detailed information.

Zoe and RJ are trying to photograph an egret on a lake, but they are having trouble with the lighting. Reflection, refraction, and absorption are explored through their thoughtful dialogue so that your physical scientists are illuminated...

At this college physics department site, the polarization of light is explained and illustrated as well as the primary methods of polarization (scattering, reflection, and refraction).

This site from Georgia State University Physics Department defines and explains the concept of potential energy. Using equations and graphics to illustrate the idea, it discusses the many types of potential energy (gravitational,...

This site from Georgia State University discusses the location of visible light on the electromagnetic spectrum. Includes the wavelength values for various colors of light within the visible light spectrum.

At this univeristy physics department site, the polarization of light is explained and illustrated. Methods for analyzing light to determine the degree of polarization are stated and explained with equations.

This site is from the Physics Department at Georgia State University. The conservation of energy as a fundamental conservation law is presented and compared to other conservation laws (momentum and angular momentum). Links to further...

This site is from the Physics Department at Georgia State University. The reliance upon the law of conservation of energy as an approach to problem-solving is presented and encouraged. It is modeled through a problem involving a...

See how this principle translates in to fluids and the Bernoulli equation as well as into electric circuits and the voltage law and finally into heat and thermodynamics through the first law of thermodynamics.
