1. The problem statement, all variables and given/known data Determine the minimum height of a wall mirror that will permit a 6ft person to view his or her entire height. Sketch rays from the top and bottom of the person, and determine the proper placement of the mirror such that the full image is seen, regardless of the persons distance from the mirror. 2. Relevant equations The Law of reflection and refraction. 3. The attempt at a solution I do not know where to start with this one. The question itself confuses me, how can the full image always be seen regardless of the distance from the mirror? What if the mirror is right up against the person? How could he possibly see his whole image? The solution in the back of the book says, "3ft with top edge of mirror at a height halfway between the persons eye level and the top of the person's head." How in the world would I go about getting this?
