Chapter 34: Refraction
As light changes from one medium to another, it can speed up or or slow down depending on the two media. This change in speed causes the wavelength of light to change. It can also change the direction of travel for the light. This "bending" of light is known as refraction. This chapter deals with a number of aspects of refraction including perceived images, effect on a lens, change in wavelength, and critical angle for total internal reflection.
