State the mirror formula for the formation of total number of images formed in two plane mirrors, held at an angle.

उत्तर
If θ = Angle of inclination between two mirrors
n = number of images formed
Then n = `360^circ/theta - 1`
Numeral one is subtracted because of the loss of one image due to the overlapping of the images.
