Vernier - Reflectivity of Light

Activity Overview

In this activity, students will use a Light Sensor to measure reflection values from paper of various colors and compare these values to reflection values of aluminum foil. They will also calculate percent reflectivity.

Key Steps

    Students set up this experiment by attaching a light sensor to a ring stand so that it is from and perpendicular to a piece of paper on the table. Students wait until the light reading stabilizes and use the SINGLE POINT measurement mode in the EasyData App.

    Students repeat this procedure several times with different types and colors of paper in order to determine their reflectivity of light.
