Question

a ray is reflected at an angle of 30 degree if the angle of incidence become double then the angle of reflection Will be​

Answer 1

Answer:

60 degree

Explanation:

According to first law of reflection incident and reflected angles are equal. So, reflected angle will be 30 degrees. Reflected angle and angle B together make up the angle between normal and the surface that is 90 degrees. So, Angle b = (90 - reflected angle), which is (90-30) = 60 degree.
