What happens when two mirrors face each other in a certain angle?

Answer 1

When two mirrors face each other at a specific angle, they create a series of multiple reflections known as an infinite mirror effect. This effect occurs due to the reflection of light bouncing back and forth between the two mirrors. Each reflection appears slightly smaller and dimmer due to the loss of light with each bounce, creating a mesmerizing visual illusion of seemingly endless reflections.

Answer 2

Depending on the angle between them, you will get multiple reflections of any object between the mirrors.

If the mirrors meet at an angle of x degrees, an object placed between them should generate a maximum of (360/n) - 1 images. Parallel mirrors should, on that basis, produce an infinite number of images but because of microscopic flaws in the mirror, absorption, internal refraction etc, the images will degrade more or less exponentially.
