you If are 6 feet tall, and want to see your full reflection at one time (while standing), how tall must the mirror be? Let h = height of object = height of virtual image d = distance of eyes top below of head s = object distance = image distance (from mirror) EPQ (base PQ, height s) and EA NB N (base h, height 2s) Therefore minimum height of mirror = PQ = h/2.
