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 ...

Join the crosses to show the paths of the light rays towards and away from ... Measure the angle of incidence, angle of reflection and angle of refraction inside the block for each block.

The Abilene Public Library invites you to join them for a magical science and art experience where kids will explore how light affects what we see! Through fun, hands-on experiments, participants ...

In a gradient, light bends towards the higher-index part, as the law of refraction predicts, or according to Fermat's principle. In a homogeneous medium (top and bottom), light does not bend. Mix up ...
