What is the formula to find the number of images formed by two mirrors?

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.

What is the formula for finding number of images?

We can find the number of images formed if we know the angle between the plane mirrors. This is given by formula: n= (360/ ϴ) – 1 if 360 /ϴ is even.

How do you find the number of images between two plane mirrors?

The number of images formed by two adjacent plane mirrors depends on the angle between the mirror. If (in degrees) is angle between the plane mirrors then number of images are given by, n = 360 θ − 1.

How many images are formed by two mirrors at 45 degrees to each other?

45 degeree=360/45 = 8-1=7 images.

What is the formula of multiple images?

The formula for calculating the number of images is (360/theta) – 1, where theta is the angle between the two mirrors. If the mirrors form 30 degrees where they meet, you will see (360/30)-1 = 12–1 = 11 images. In the barber’s saloon, the mirrors are placed parallel to each other. So there are 360/0 = infinite images.

How are multiple images formed on the mirror?

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 process continues till no more reflection by either mirror is possible.

What is the formula for the number of images formed by mirrors?

Originally Answered: What is the formula for the number of image formed by two plane mirrors when the angle between the two mirrors are given? Let the two mirrors be inclined to each at angle x, then the number of images that is formed of an object between the two is (360/x) – 1. Then the number of images formed = (360/60)-1 = 6–1 = 5.

How many multiple images are formed by two inclined plane mirrors?

– Answers Formula of number of multiple images formed by two inclined plane mirrors? 360/the angle of inclination-1= the number of multiple images formed. Q: Formula of number of multiple images formed by two inclined plane mirrors?

How many images can be drawn from a 72 degree mirror?

Let (theta) be angle between two mirrors then if 360/ (theta) is odd then number of images will be=360/ (theta). For (theta)= 72 degree this ratio is 5, so number of images is 5. If the above ratio is even ,then number of images will be= [ (360/theta)-1].

Is there an infinite number of images in a 360 degree angle?

If the angle is an irrational multiple of 360°, then there is a denumerable infinity of images. Not all images will be visible from a single point of view; an additional mirror or a refractor would be necessary to see images around the axis of relative orientation of the mirrors.
