why are multiple image formed when two plane mirrors are placed at some angle to each other
Answers
Multiple images are formed when two mirrors are placed at right angle to each other because when a ray incident on first mirror from an object it forms an image of the object. This image acts as object for second mirror and then a ray incident on second mirror from the image formed on first mirror, it then also forms image on second mirror. So further image of image are also formed. This process continues till no more reflection by either mirror is possible. This phenomenon is known as multiple reflection. The number of images formed when two mirror are placed at right angle are three.
Explanation:
When two mirrors are kept at an angle and an object placed in between the mirrors, multiple images are formed due to reflection from one mirror on to the other. The number of images of the object formed depends on the angle between the two mirror
