simulation to see how waves spread, interact, and behave in different mediums.

Activity: Light Refraction

Objective

Overview

Materials

● Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows. ○ Explain how light bends at the interface between two media and what determines the angle. ○ Describe how the speedand wavelength of
