Question

why are multiple images formed when two Mirrors are placed at right angles to each other

Answer 1

If you place two mirror at an angle, rather than one multiple images are formed. This is because the image formed in the first mirror acts as the object for the second mirror.

In this case, if you place the mirrors at right angle (90°), then the formula 360/n -1 is used, where n is the angle between the mirror.

Here, n= 90. So,

360/90–1

=4–1 = 3.

Therefore, 3 images will be formed.

Answer 2

Hey Mate !!! Here is your answer !!

When two mirrors are placed in right angles, incident ray strike on one mirror and reflects to another mirror in the perpendicular direction.
This is one of the main reasons why multi images are formed when two mirrors are placed.
