The Speed of Light in Glass
What happens to the speed of light as it goes through a glass door? Light travels slower through glass than through air, but does the speed of light change or is it just our perception? The short video explains the speed of light as it...

Transverse and Longitudinal Waves
Transverse waves and longitudinal waves each have unique properties. Young scholars learn these differences, the measurements of waves, and a formula for calculating the speed of the wave.
Berkeley University of California
Radiation Properties
How are the wavelength, frequency, and speed of a wave related? The instructor in the video explains the process of determining the frequency of a wave with a known speed and wavelength. The wave is then classified along the...

Fast Neutrinos
According to Einstein's theory of special relativity, nothing can go faster than the speed of light, but Einstein didn't know about neutrinos. In fact, physicists are just beginning to be able to study these tiny particles that zip...

Measuring Speed of Light
A beam of laser light is sent to a satellite from a transmitter and travels 40,000 km. Elapsed time is recorded. This is all done to prove that the speed of light is 300,000 km/sec. This interesting clip can be used when you teach young...
