When a converging lens is used in a camera (as in the first drawing), the film must be placed at a distance of 0.160 m from the lens to record an image of an object that is 4.00 m from the lens. The same lens is then used in a projector (as in the second drawing), with the screen 0.530 m from the lens. How far from the projector lens should the film be placed? Film Real mage inverted) Object...

A cheap replica is made of an old camera. If the lens in the old camera was glass, and the lens in the replica is plastic with a smaller index of refraction than the glass, in order to have the same focal length the plastic lens will have to ______. a. be less strongly curved than the glass lens b. have the same curvature as the glass lens c. be more strongly curved than the glass lens
A camera with a 50.0 mm focal length lens is being used to photograph a person standing 2.43 m away. How far from the lens must the film be? You need to express your answer in cm, do not include unit. Your answer should be a number with two decimal places.
