Question

An illuminated object is placed between two plane mirrors mutually perpendicular to each other how many images are formed?

Solution

Correct option is

Three

 

The number n of the images seen is given by  

                               

Where n is the least value of the integer which satisfies this condition. For θ = 90o, the least integral value of n = 3.
