A Ray of light is incident on a plane mirror making an angle of 90∘ with the mirror surface. The angle of reflection for the ray of light is ____degree.

Question

Accepted Answer

Concept- The angle of reflection for the ray of light is 0 degree. The second law of reflection can be applied to: According to the second law of reflection, the angle of incidence and angle of reflection are always identical. As a result, due to the angle of incidence, the angle of reflection is also the same.
In this question, a ray of light is shown falling on a plane mirror.
It forms a 90-degree angle with the mirror's surface.
The angle of reflection for the Ray of light is given to us.
To solve this problem, we must first understand the laws of reflection.
There are two reflection laws. They have
(1) The incident ray reflects the ray, and the normal is in the same plane as the incident ray.
(2) The incidence angle will be equal to the reflection angle.
The incident ray is the falling ray in this case. The normal is the line drawn perpendicular to the surface of the mirror at the point of incidence.
The angle of incidence is defined as the angle formed by the incident ray and the normal.
The angle of reflection is the angle formed by the reflected ray and the normal.
It is already assumed that the incident ray forms a 90° angle with the mirror surface. This indicates that the incident ray intersects the normal line drawn at the point of incidence. As a result, there will be no angle between the incident ray and the normal. As a result, the angle of incidence is zero.
We know that the angle of incidence and angle of reflection should be equal according to the law of reflection. Because the angle of incidence is zero, the angle of refraction should be zero as well.
Hence, the correct answer is 0 degree.

A Ray of light is incident on a plane mirror making an angle of 90∘ with the mirror surface. The angle of reflection for the ray of light is ____degree.
