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 ...

In 1943, the two German scientists Goos and Hänchen performed an experiment showing that in total internal reflection a light beam acquires a lateral shift; this can be seen as a positional ...

Join the incident ray to the emergent ray to show the path of the light through the block. Repeat steps 2 to 8 for a rectangular glass block. Measure the angle of incidence, angle of reflection ...
