Question

a small object is kept symmetrically between two plane mirrors inclined at 38°. this angle is now increased to 41°,the object being symmetrical all time . determine number of images visible during process

Answer 1

Explanation:

Use the formula

Y = 360/x

where x = angle between the mirror

y = no. of images

if the object is placed symmetric to both the mirrors, subtract 1 from Y because the two formed images overlap on each other.

For unsymmetrical placement of object, Y is the answer.

For your case,

Symmetric placement, Y = 360/75 - 1 = 3 (complete images)

unsymmetric placement, Y = 4

The value 0.8 represents an incomplete image.
