MP Board · Class 8 · Science · LightAn incident ray makes an angle of 30 degrees with the reflecting surface. What is the angle of incidence?
Step-by-Step Solution
The angle of incidence is the angle between the incident ray and the normal drawn at the point of incidence. Since the normal is perpendicular (90 degrees) to the surface, the angle of incidence is 90 - 30 = 60 degrees.
