Image obtained with a concave lens

Principle

The students' unsuccessful attempts at capturing images formed by a convex lens make this experiment especially interesting and motivating when they have no or only uncertain knowledge of image formation at a convex lens. However, this experiment is also highly recommended to confirm or test students' theoretical knowledge. Even in this situation, many students will attempt to intercept the image against their better judgement.

Benefits

• Multifunctional light box - All-in-one: Can be used for geometric optics on the table, colour mixing and on an optical bench
• Extension with others sets at anytime, no additional light sources needed, recognition value for students

Tasks

What are the properties of images formed by concave lenses? Investigate the properties of images formed by a concave lens for different object distances.
