Suppose a man stands in front of a mirror. His eyes are 1.65 m above the floor, and the top of his head is 0.13 m heigher. Find the height above the floor of the top and bottom of the smallest mirror in which he can see both the top of his head and his feet. How is this distance related to the man's height?
A person stands at a distance of 3.6 m in front of a wall covered with a plane mirror from the floor to the top his eyes are at 1.8 metres above the floor he holds a Flashlight between his feet and managed to point it at the mirror. At what angle of incidence must the light strike the mirror so that the light reaches his eyes
A man stands 1.00 m in front of a plane mirror. His eyes are 1.75 m above the ground. The top of the mirror is level with his eyes. How long must the mirror be in order for him to see his shoes in the mirror, assuming that he is standing with both feet firmly on the floor? Does his distance from the mirror matter?
