Question

The experiment set-up shown in the picture has a light-proof box with a small hole on one side. What will be the shape of the image of the arrow on the opposite wall?

(The arrow is pointing up in the image of the arrow, also the box has a hole on it's left side.)

A. Left
B. Up
C. Down
D. Right

Answer 1

Answer: A.

Explanation: When light passes through a small hole, it creates an inverted image on the opposite side. In this case, since the arrow is pointing up, the inverted image will appear pointing down on the opposite wall. Furthermore, since the box has a hole on its left side, the inverted image will be shifted towards the left.
