Question

Hey guys,
Can someone help me with this question?

Two plane mirrors are inclined to each other at an angle 60°. If a ray of incident on the 1st mirror is parallel to the other, it is reflected from the 2nd mirror...

a) Perpendicular to Mirror 1
b) Parallel to Mirror 1
c) Parallel to Mirror 2
d) Perpendicular to Mirror 2

If can pls send diagram too. Thx
​

Answer 1

Answer:

Correct option is

B

Parallel to the first mirror

Let θ be the angle between the two mirrors OM

1

and OM

2

The incident ray is parallel to mirror OM

2

and strikes the mirror OM

1

at an equal incidence angle.

From the given figure above

∠M

1

BA=∠OBC=∠M

1

OM

2

=θ

Similarly ∠M

2

CD=∠BCO=∠M

1

OM

2

=θ

From △OBC

3θ=180

∘

⟹θ=60

∘

So, reflected ray is parallel to first mirror
