Expert Answer

When two mirrors are inclined at an angle, then the number of images is decided by the ratio of 360/θ.

Here, 360/θ is even. Therefore, the number of images formed is always n = 360/θ - 1 = 360/60 - 1 = 6 - 1 = 5.

Hence, the correct answer is option A.

If however, 360/θ is odd, then

(i) The number of images is n when the object is placed asymmetrically.

(i) The number of images is n - 1 when the object is placed symmetrically.
