Question

how many images will be formed if an object is kept between two plane mirror parallel to each other

Answer 1

When an object is placed between two plane mirrors parallel to each other then infinite number of images are formed.
Hence infinite number of images will be formed.

Answer 2

Infinite images will be formed.

• So, let's assume that an object is placed in the middle of two parallely placed plane mirror.

• Now, the angle between the mirrors is zero (0°).

So, the number of images will be :

$\therefore \: m = \dfrac{ {360}^{ \circ} }{ {0}^{ \circ} } = \infty$

• This is usually experienced when we visit barber shops for hair cut. There are two such parallel mirrors. When we sit on a chair in between the mirrors, we get to see infinite images of us being formed.
