How many images will be formed if an object is kept between two mirrors inclined at an angle of 0 degree?
Answers
Answer:
Formula for number of images formed by two plane mirrors incident at an angle θ is n = 360∘θ. If n is even, the number of images is n-1, if n is an odd number of images.
Answer:
If you start with two mirrors at an angle with each other, and there’s a hinge (axis of rotation) to vary the angle till you get down to zero, the distance is also zero. Then the answer is simple. No light can get in and no images will be formed.
But if there’s some distance between them, the each mirror will form an image of the other. But the image of a mirror in a mirror will also behave like a mirror. So it will also add a reflected image - which also contains a mirror. This repeated reflection goes on forever in principle. So an infinite number of images are formed.
In reality, some light is lost with each reflection. It’s never perfectly 100% reflected. So each successive image gets darker and darker until you cannot detect it.
