Question

State whether true or false:

Diaphragm in a photographic camera control the time of exposure of film.

• A. True
• B. False

Answer 1

The correct option is B False

Answer is B.
The size of the diaphragm opening in a camera lens regulates the amount of light passes through onto the film inside the camera the moment when the shutter curtain in camera opens during an exposure process. Therefore, the shutter is responsible for controlling the time of exposure of film in the camera.
Hence, the statement is false.
