You want to make a real image of a smartphone screen, and you want this image to be twice as large as the original screen. You also want the distance from the smartphone screen to the real image to be exactly 60cm. (the image may be inverted; that's fine if it is) A) Calculate the focal length of the lens you will need to make this happen. (Warning: I didn't give you either s or s', because I didn't give you any distances to the lens. So one of the first things you will need to do is to figure out exactly where the lens needs to be.) B) Show a ray-tracing diagram of your answer from part A. Be sure to only show the usual three special rays, no more, no less. Three shall be the number of the rays, and the number of the rays shall be three. 51°F 8:47 PM Clear…Which option is best to do among (a-d)? USE IMAGE AS REFERENCE.
