A camper is trying to start a fire by focusing sunlight onto a piece of paper. The diameter of the sun is 1.39 × 109 m, and its mean distance from the earth is 1.50 × 1011 m. The camper is using a converging lens whose focal length is 14.0 cm. (a) What is the area of the sun's image on the paper? (b) If 0.339 W of sunlight pass through the lens, what is the intensity of the sunlight at the paper?
