Question

THE NUMBER OF IMAGE FORMED BY THE TWO PLANE MIRROR IS INCLINED AT AN ANGLE DEPENDS ON

Answer 1

The answer to the question is that: the number of images formed by the two plane mirrors at an inclined angle  depends upon that specific angle between the two plane mirrors.
The two things are going to occur :The angle of incidence (i) is equal to the angle of reflection (r).
                                                      : The incident ray, reflected ray and the normal to the surface at the point of incidence all lie in the same plane.
 You can use the following formulas to find the number of images formed:

If the value of 360/x is even, then we will use the formula

no. of images= 360/x -1

If the value of 360/x is odd, then we use the formula

no. of images= 360/x

Hope  this helps !! thankyou & goodbye !! :)
