In this type of application, engineers mount the retroreflectors individually on an aluminum plate, placed very tightly together so that the array acts as a large, self-compensating mirror surface. As another example, hollow retroreflectors better than 1 arc sec al ...

Refraction - Snell`s Law, Internal Reflection, Dispersion (PowerPoint)
... The fact that rainbows are semicircular tells you that the light from one has to come from the water drops at the right angle angle*. When white light enters a water drop light is refracted and disperses into its component colors. Violet is bent the most and red the least. When the rays reach the op ...
