Refraction is an important behavior of light that can be used to explain the operation of lenses, prisms, and optical fiber, as well as natural phenomena such as rainbows and mirages. The index of refraction, or refractive index, is defined as the ratio of the speed of light in a vacuum to the speed...

In this video from the ICT Center, learn about interference and diffraction. See how the wave properties of light are used to explain interference patterns on a screen, and learn about related technologies such as the Fabry-Perot cavity, Bragg gratings, interference filters, and antireflection...

This video from Laser-Tec is part of a series of light and optics experiments. In this lab, participants explore interference and diffraction through a pinhole. Participants learn about the diffraction of light when it passes through a pinhole and calculate the radius of a central airy disc....
