Light Refraction

Published on 07/15/2011

Activity Overview

In this lesson, students visually explores refraction of light as it passes through different substances with different indexes of light.

Objectives

  • Students will observe the path of light as it moves from one medium to another.
  • Students will relate the angle of incidence to the angle of refraction.
  • Student will determine the equation relating the angle of incidence, angle of refraction, and the refractive index of each medium that light is passing through.

Vocabulary

  • angle of incidence
  • angle of refraction
  • refractive index
  • Snell’s Law

 

About the Lesson

This lesson visually explores refraction of light as it passes through different substances with different indexes of light.
As a result, students will:

  • Understand the how light is bent when it passes through a different medium.
  • Be able to calculate the angle of refraction based on the ratio of the indexes of refraction
