Question

if the angle of incidence for a ray of light is 40°, then its angle of refelction will be____________​

Answer 1

Answer:

If the angle between the incident ray and mirror is 40 degree , then the angle of incidence will be 50 degree. Then the angle of reflection will 50 degree ( angle of incidence = angle of reflection).

Answer 2

Answer:

Its angle of reflection will also be 40° as the law of reflection states that angle of incidence is equal to the angle of reflection on the same plane.
