6A10.31 - Mirrors - Large Corner Cube Reflector

Code Number:
6A10.31
Demo Title:
Mirrors - Large Corner Cube Reflector
Condition:
Excellent
Principle:
Reflections Set at 90 Degrees
Area of Study:
Optics
Equipment:
Corner Cube Mirror Demos, and Laser.
Procedure:

Another mirror set and 90 degrees to the two perpendicular mirrors will produce a straight back reflector as can be demonstrated with a laser.  Shine the laser into any place of the corner reflector and the ray will be reflected back to the point of origin.
