An underwater camera has a lens of focal length 35 millimeter and a maximum aperture of f/2.80. The film it uses has an emulsion that is sensitive to light of frequency 5.70 × 1014 Hertz. If the photographer takes a picture of an object 2.85 meter in front of the camera with the lens wide open.
a) Find the width of the smallest resolvable detail on the subject if the object is a fish underwater with the camera in the water?
b) Find the width of the smallest resolvable detail on the subject if the object a person on the beach, with the camera out of the water?
