In a room, Quinton is standing at the north end, and Tallulah is at the south end. A tall bookshelf is placed between them, reaching from the floor to the ceiling, effectively blocking their direct line of sight to each other. If Quinton places a mirror on the east wall facing west, and Tallulah has a mirror facing east on the west wall, both at the same height and angle, what happens when Quinton looks into his mirror?

Provide a very brief response.
When Quinton looks into his mirror, he sees the reflection of Tallulah's mirror on the opposite wall if both mirrors are aligned properly. The light from Tallulah's side of the room will reflect off her mirror, travel across the room over the top of the bookshelf, and then reflect off Quinton's mirror into his eyes. This will only happen if there is a clear line of sight between the two mirrors over the top of the bookshelf, and the mirrors are angled correctly to allow the light path to connect them. If the mirrors are not aligned, Quinton would see only the reflection of other parts of the room or objects within.
