CHAMPAIGN–

Mats Selen U of I Physics professor joins us to talk about light and color. 

–          Light is a wave

–          The wavelength of the light determines the color of the light.

–          White light is made up of spectrum of different colors, from longer wavelength red to shorter wavelength                    blue.

–          White light can be broken into its constituent colors using a prism or a diffraction grating.
