Physics: Lenses and Light

Objectives

• Students will explore the direction of light rays through concave and convex lenses.
• Students will determine the affect the focal points have on light rays leaving a lens.
• Students will explore the images that are produced from concave and convex lenses.

Vocabulary

• concave
• converging
• convex
• diverging
• focus, foci, focal length
• real image
• virtual image

About the Lesson

In this lesson, students will explore the characteristics of lenses.
As a result, students will:

• Develop an understanding of the affect different types of light have on light rays.
• Relate the effect of a light ray to the focal point of a lens.
• Explore the relationship of objects to the images that are produced when light passes through a lens.
