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 ...

Biv.” A rainbow is a spectrum of visible light. Each color has a different wavelength. To separate white light into these colors, the light needs to pass through a material that “bends” it. This ...

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 ...

Dependent Variable is the angle of refraction ... light will bend from a bigger initial angle, and so the angle of refraction will also be bigger. Low voltage power pack, a 12V ray box, a single ...
