Chapter 37: Interference
Because light is a wave, the light from two or more sources can interfere to yield distinctive patterns. The different colors of a bit of oil in a water puddle is an example of an interference effect. In this chapter, you will explore the interference of light from multiple sources using a virtual ripple tank in order to make the connection between path length difference and interference. You will also explore the interference of light incident on thin films.
