An object P is kept in front of two plane mirrors as shown in the figure. The number of images formed is k . Find out the value of k .

Correct answer

Step-by-step solution

The above diagram represents the angular positions of possible images that can be formed in the given case. Since, images further than 180 ° will not be visible, we obtain the maximum number of visible images as 5 .
