Problem: A 35 mm camera has a rectangular array of CCDs (light sensors) that is 24 mm by 36 mm. It is used to take a picture of a person 169 cm tall so that the image just fills the height (24 mm) of the CCD array.
Part A: How far should the person stand from the camera if the focal length of the lens is 63 mm?
I want help to find how far the person should stand from the camera if the focal length of the lens is 63 mm.
