Reflectivity of Light
Recommended for grades 5–12.
Introduction
Light is reflected differently from various surfaces and colors. In this experiment, you will be measuring the percent reflectivity of various colors. You will measure reflection values from paper of the various colors using a Light Sensor and then compare these values to the reflection value of aluminum foil. You will then calculate percent reflectivity using the relationship:
Objectives
In this experiment, you will
- Use a Light Sensor to measure reflected light.
