Problem 58
Q

The normal lens on a 35-mm camera has a focal length of 50.0 mm. Its aperture diameter varies from a maximum of 25 mm (f/2f/2) to a minimum of 3.0 mm (f/16f/16). Determine the resolution limit set by diffraction for (f/2f/2) and (f/16f/16). Specify as the number of lines per millimeter resolved on the detector or film. Take λ\lambda = 560 nm.

A
f/2: 730 lines/mm, f/16: 88 lines/mm
