I have 2 questions: What type and height of image would a rearview mirror produce of a car that was 1.3 m high and 15.0 m behind you, assuming the mirror's radius of curvature is 3.2 m? I don't know what equation to use to solve the problem. I think it might be: (1/object distance) + (1/image distance) = 1/f However, w/ this equation I don't know where to plug in the height (1.3 m). Please help! The other question is: A mirror at an amusement park shows an upright image of any person who stands 1.3 m in front of it. If the image is three times the person's height, what is the radius of curvature? However, I don't understand how to solve it if we don't know how big the image is. I also know that f=r/2, which I might need later on in the problem. Thanks!
