1. The problem statement, all variables and given/known data While you were looking at the reflection of your feet in a plane mirror, you saw a dark spot on the glass. Assuming your height is 1.50 m, and that the eyes are located 0.1 m below the top of the head (a) What is the distance between the spot and the floor? (b) What is the minimum amount of mirror needed to see your entire image? 2. The attempt at a solution I have correctly solved part (a) using a scaled diagram; however, I am having a hard time understanding part (b). This is because, logically, wouldn't your position, relative to the mirror dictate the amount of mirror needed to see the entire image? If someone could please point me in the right direction. Thank you.
