Transverse and Longitudinal Wave Propagation in an Elastic Medium
Extensive information about how waves behave in an elastic medium. Covers different types of waves, their characteristics and behavior, the anatomy of the ear, the speed of sound in different media, the parts of a wave, and wave phenomena.
Physics Classroom
The Physics Classroom: Light Waves and Color: Thin Film Interference
Students investigate an example of interference that provides further evidence in support of the wavelike behavior of light.
Exploratorium
Exploratorium: Critical Angle
Students can see light reflected and refracted in this demonstration. They will also discover the total internal reflection of light.
