6A10.40 - Mirrors - Mirrors at an Angle

Code Number:
6A10.40
Demo Title:
Mirrors - Mirrors at an Angle
Condition:
Excellent
Principle:
Reflections
Area of Study:
Optics

Disclaimer

Equipment:
Mirror Demo, Poster with Large Writing, and Adjustable Angle Mirror.
Procedure:

Video Credit: Jonathan M. Sullivan-Wood

Clean the mirrors thoroughly before use.  When moving the demo use care over bumps so a not to break the flat mirror.  Hold a poster with writing on it before the mirrors and the words will be backward and unreadable in the flat mirror but readable in the mirrors set at 90 degrees.

Varying the separation of the mirrors and providing a slight offset should give you a position showing a maximum amount of reflections.
