L1-21. Pinhole Image - Ground Glass Screen
Purpose
To view individually a pinhole "image".
Equipment
Box with pinhole and movable ground glass screen.
Suggestions
Point out that a pinhole "image" is not really an image at all. What is it?

Description
A pinhole in the back end of the outer box casts an "image" on a ground glass screen at the enclosed end of the inner box. The image is viewed through the open end of the box as the inner box is slid back and forth to change the size of the image.
