| The number of images formed for 
                    a combination of plane mirrors depends on the angle between 
                    the mirrors. If q be the angle between the two mirrors, then 
                    the number of images formed is given by, No. of images, n= 360/q -1
 Only the whole number part of n is taken. Further, if n is 
                    even then, n = n-1. That is only odd number of images are 
                    formed. For example, if for some value of q, n = 6.2, then n=5.  How do these images form? check out the animation.
