Question

Angle between incident ray and reflected ray​

Answer 1

Explanation:

The normal line divides the angle between the incident ray and the reflected ray into two equal angles. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection.

Answer 2

Answer :

Clearly, we can see that line A is incident ray and line B is reflected ray and N is the normal line. Now, we know that the normal line always divides incident ray and reflected ray into equal angles. We have :

• Angle of incident ray = 30°
• Angle of reflected ray = r

Hence, r = 30°.

Therefore, angle of reflected ray = 30°.

Hence, Angle between incident ray and reflected ray = 30° + 30° = 60°.
