Answer 1

Answer:

Angle of incidence is 50°

Explanation:

Hope this helps u

Answer 2

Solution :-

Here , the mirror has made angle of 50° with a ray and in the given figure there is a normal .

So , here as we know that angle between normal and the mirror is 90° , here theres a ray in between the mirror & normal

So ,

⇒ 50° + angle of incident = 90°

⇒ Angle of incidence = 90° - 50°

⇒ Angle of incident = 40°

Hence , angle of incident = 40°
