Question:
The wall of a room was covered with a perfect plane mirror and two films were made one film was made by recording the movements of a man and the other that of his image later by viewing the two films how can we distinguish between the two
Answer:
Due to left-right symmetry, an outsider cannot distinguish between the two films. However, if any asymmetrical initial information such as, if the man is left hander; etc is there, he can distinguish between the two movies. It is because, the image produced by a plane mirror is laterally inverted.
