Code Number: 6A20.41

Demo Title: Mirrors - Projected Image with a Curved Mirror

Condition: Excellent

Principle: Concave Mirrors, Focal Lengths, Imaging

Area of Study: Optics

Equipment:

Large Concave Mirror, gooseneck lamp, light bulb with a painted letter "F" on it, Black Board optics board if desired.

Procedure:

Place the 100 watt light bulb with the letter "F" painted in black on it into the gooseneck lamp. Place it at the focal point of the large concave mirror with the letter "F" facing the mirror. Turn the mirror slightly so that the real image may be focused on the screen or Black Board optics board.
