If you take a picture of your friend, who is standing 3.90 m from the lens, using a camera with a lens with an 85-mm focal length, how far from the sensor is the lens? Express your answer to three significant figures and include the appropriate units. Will the whole image of your friend, who is 175 cm tall, fit on a sensor that is 24 mm times 36 mm? It will fit. It will not fit.
