how can we calculate the image between two plane mirrors inclined at an angle a????????

i dont understand that whose image you are going to calculate

and whatss this calculation mean

is it the number of images or anything else

also the size of image is not defined

for infinitely large mirror it is unpredictable

and infinite number of images will be formed in this case

For an object kept between two plane mirrors inclined at angle a (in radians) ,

the total number of images formed is given as , 2∏/a -1

Please rate my answer.
