To investigate the reflection of light by different types of surface, and the refraction of light by different substances. Remove the block. Join the crosses to show the paths of the light rays.

Explores the principles of light, reflection, and magnification through hands-on experiments. Children observe how a magnifying glass focuses sunlight to create heat, examine the effects of light on ...

However, if this would bring the ray out at more than 90° from the normal, the refraction is not possible. In this situation, the ray is reflected inside the more dense medium, following the law of ...

I test a series of light experiments to explore reflection, refraction, and optical illusions, demonstrating how light ...
