If I stand between two plane mirrors on opposite walls in a room, I observe multiple images. When I stand 5 m from the mirror on the left wall, and 10 m from the mirror on the right wall, what are the distances (in meters) from me to the first three images seen in the mirror on the LEFT? I know how to calculate the distance of an object with one mirror, but two throws me off because of the multiple reflections. My teacher hasn't discussed this and I can't find anything like it in my text book. Can anyone help?
