Concave Mirror

Purpose:

To show how 'real' a real image can be -- really!

Procedure:

Arrange box and mirror so that a real image of the light bulb appears over the empty socket on top of the box. The mirror should be placed about 82-85 cm. from the base of the box and positioned so that students entering the classroom can observe the real image.

Hints:

Use the shims under the base of the mirror for better leveled image.
