Text Solution
Verified by Experts
The origin of multiple images is the multiple reflection of light between the front and back surface of glass. Infact, at the front surface of glass, light is partially reflected and partially refracted. The refracted light gets reflected at the back surface and then multiple reflections follow within the thickness of glass. They are responsible for multiple images.
