L2-41: OPTICAL BOARD - CORNER REFLECTOR
- ID Code: L2-41
- Purpose: Show how a corner reflector works in two dimensions.
- Description:
A ray of light strikes the two surfaces of the corner reflector and returns antiparallel to the original light ray. For a three-dimensional corner reflector the outgoing light ray also leaves antiparallel to the incoming light ray. The lens keeps the ray narrow.
A set of three rays of different colors can also be used with this two-dimensional corner reflector to show that the rays return inverted with respect to their initial orientation.
