Question

The angle between the incident ray and the reflected ray is 100°. What is the value of the angle of incidence?

Answer 1

So the angle between both the angle of incidence and angle of reflection is 50 + 50 = 100 degrees.

pls mark me as brainliest answer pls...

Answer 2

Angle of incidence is $50^{o}$.

Explanation:

• Law of reflection states that when any ray is incident on a reflecting surface, the reflecting ray will reflect with the same angle. It means the angle of incidence is equal to the angle of reflection.

• Angle of incidence is the angle made by incident ray with the normal.

• Normal is a perpendicular line at the interface of two mediums.

• Angle of reflection is the angle made by reflecting ray with the normal.

• Since, angle between reflecting ray and incident ray is $100^{0}$, and normal bisects this angle into equal parts, i.e. angle of incidence and angle of reflection.

• Therefore, angle of incidence = angle of reflection = $50^{0}$
