Condition :	Excellent
Principle :	Reflections Set at 90 Degrees
Area of Study :	Optics
Equipment :	Corner Cube Mirror Demos, 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.
