Question

An object is kept asymmetrically between two plane mirrors inclined at an angle of 72°. Find the total number of images formed by the mirrors.​

Answer 1

Answer:

The number of images formed if two plane mirrors are kept at an angle θ is given by, 360oθif360oθ 360 o θ i f 360 o θ is odd and it is given by 360oθ−1if360oθ 360 o θ − 1 i f 360 o θ is even. For θ = 72o, number of image is 360o72o=5 360 o 72 o = 5 as 360o72o=5 360 o 72 o = 5 is an odd
