Could somebody please help me on the following questions:
1. A camera with a 50mm focal length lens focuses on a man 1.8m tall standing 40m from the camera.
(a) What angle does the man subtend at the camera lens?
[I do not know what subtend means]
(b) What is the size of the image of the man on the film?
