Lesson: Concave Lenses Science

In this lesson, we will learn how to identify the optical properties of concave lenses.

Lesson Plan

Students will be able to

describe what a lens is,
describe what a concave lens is,
identify the optical axis of a concave lens,
identify the center of curvature of a lens,
describe what is meant by the term diverging,
identify the radius of curvature of the lens,
recall that the focal length of a lens is the distance between the center of the lens and its focal point.

Q1:

Which of the following statements correctly describes what is meant by diverging light rays?

Q2:

Which of the following is a concave lens?

Q3:

Which of the following is the correct definition of the focal length of a lens?
