Question

two plane mirrors are at right angle to each other a man stands between them and combs his hair with his right handin how many of the images will he been seen using his right hand

Answer 1

The number of images formed when two mirrors are placed at an angle theta to each other is given by:

n = ( 360 / theta ) - 1

now we have placed mirrors at right angle so theta=90

n=(360/90)-1
n=4-1
n=3

so the total no. of images will be 3

Answer 2

Answe is one because other two will show using his left hand.
