LIGHT ©2008 e-learning @Science-tutors The relationship of the angle between the mirrors (A) to the number of images (N) is expressed as A(N+1) = 360. N+1 = 360 º ÷A N = 360 º -1 ÷ A Where N is the number of images formed between two mirrors inclined at any angle.

The relationship of the angle between the mirrors (A) to the number of images (N) is expressed as A(N+1) = 360.

N+1 = 360 º ÷A

N = 360 º -1 ÷ A

Where N is the number of images formed between two mirrors inclined at any angle.
