Question

If two mirrors are inclined at some angle V . an object is placed between the mirror an dthree are 5 images formed for an object, then $\theta$ is amy be

Answer 1

no of image between two inclined plane found by ---

M = 360°/Ө

if M = any natural number , then only this is not occur when object placed bisector of angle of line ,

no of image = (m-1) now ,

here 5 image formed between two mirror,

so, 5 = M-1

M = 6

so, 6 =360°/ Ө

Ө = 360/6 =60°

hence , this is nearly equal to 60°
