L4-06. Refraction In Cloudy Water
Purpose
Demonstrates how a light ray bends when it enters a different medium at an oblique angle.
Equipment
Laser with plastic tank containing water with powdered creamer.
Setup Time
5 minutes.

Description
The ray from the laser refracts when entering the surface of the cloudy water. The path of the laser beam in the water is rendered more visible by adding a touch of powdered creamer to the water.
