Answer :
60° is the correct Answer .
Two mirrors meet at right angles a ray of light is incident on one at the angle of 30° the reflected ray from the second mirror is 60°
More Information :
In this Question, It is given that two Mirrors meet at right angles a Ray of light is incident on one at the angle of 30°.
Refer to Attachment : Diagram shows that the Direction of reflected ray from the second mirror which shown in the figure. Thus, incident ray on the mirror 1st is 30°.
So, Emergent ray will be ( 90° - 30° ) i.e 60°
Extra Information : ( Laws of Reflection )
From the laws of Refraction , Angle of incidence is Equal to the angle of Refraction. i.e ∠i = ∠r

two Mirrors meet at right angles A Ray of light is incident on one at the angle of 30° the reflected ray from the second mirror is 60° .
Diagram shows that Angle of incidence is 30° on the both mirror i.e First and Second mirror.
From Diagram 90 - 30 = 60 Degree.
Therefore, the reflected ray from the second mirror is 60°

Similar questions
{Angle of incident ray= angle of reflected ray}
So as,
Angle of incident in [30degree]
Angle of reflected ray on the second mirror will be the same [30 degree]
Hope this helps u
