Number of images formed by two plane mirrors formula derivation

Answer:

Explanation:

Use the formula

Y =  360/x  

where x = angle between the mirror

y = no. of images

if the object is placed symmetric to both the mirrors, subtract 1 from Y because the two formed images overlap on each other.

For unsymmetrical placement of object, Y is the answer.

For your case,

Symmetric placement, Y = 360/75 - 1 = 3 (complete images)

unsymmetric placement, Y = 4

The value 0.8 represents an incomplete image.

Originally Answered: What is the number of images when the angle between two plane mirrors is 75 degrees?

360/75 = 4.8 say 4.

So the numbers of images will be 4–1 = 3.
