Lesson: Ray Tracing Physics • 9th Grade

In this lesson, we will learn how to represent the paths of light rays that pass through regions of various media that have various shapes.

Lesson Plan

Students will be able to

interpret ray diagrams to identify parallel, converging, and diverging rays,
interpret ray diagrams to identify the reflection and refraction of rays,
identify the optical axes of objects.

Lesson Worksheet

Q1:

The diagram shows a semicircular object and some lines which could be the optical axis of the object. Which line correctly represents the optical axis?

Q2:

The diagram shows a curved object and some lines that could be the optical axis of the object. Which line correctly represents the optical axis?

Q3:

Which of the following diagrams could correctly represent the paths of a set of parallel light rays that arrive at the surface of the curved object shown?
