Question

60. Two plane mirrors are arranged perpendicular to
each other. If a light ray is incident at 30° on one
of the plane mirrors of above arrangement, then
find
(a) Angle of reflection at the second plane mirror.
(b) Angle of deviation at both the mirrors.
(c) Number of images that we can observe when
one plane mirror is rotated by 30° towards the
other.​

Answer 1

Answer:

hii dude

here is your answer the angle of reflection on second mirror will be 60°

angle of deviation on first mirror will be 120° and angle of deviation on second mirror will be 60°

no of images will be

N=360/angle-1

=360/90-1

=3 images

please mark me as brainlest I need it very much
