Explanation

The correct answer is option 3 i.e. 2.

  • The formula to find the number of images formed between two plane mirrors inclined at an angle,  between them is as follows:

          Number of images formed = (360° ÷ ) - 1

  •  = 120°

         Number of images formed = 

                       (360° ÷ 120) - 1 = = 3 - 1 = 2
