What is the formula to find number of images formed when two plane mirrors are inclined at an angle?

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 the number of images formed by two plane mirrors?

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 many images are formed when two plane mirrors are placed at 45?

Seven images will be formed; as the number of images formed in two plane mirrors inclined at an angle of 45o¸ is given by, n = (360o / θ) – 1 = (360o / 45o ) – 1 = 8 -1 = 7. Explain why, when an object is placed between two plane mirrors inclined at an angle, then multiple images are formed.

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 many images will be formed?

Infinite images will be formed if the object is kept between two plane mirror facing each other.

How many numbers of images will be formed when two plane mirrors are placed at an angle of 60 degree to each other?

60 degeree=360/60 = 6-1=5 images.

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 images are formed when two plane mirrors are inclined?

If the image of an object is viewed in two plane mirrors that are inclined to each other more than one image is formed. The number of images depends on the angle between the two mirrors. The number of images formed in two plane mirrors inclined at an angle A to each other is given by the below formula.Number of images n= 360/A – 1

How many images are formed when an object is placed between?

When an object is placed between two perpendicular plane mirrors, three images are formed as shown in the ray diagram. Multiple images of are formed when an object is placed between two mirrors at an angle ( θ ).

What is the angle a between the mirrors?

As the angle gets smaller (down to 0 degrees when the mirrors are facing each other and parallel) the smaller the angle the greater the number of images. Here, the angle A between the mirrors is 40 degrees. Case (a): The object is symmetrically placed.
