Question

What are the laws of reflection? ​

Answer 1

Answer:

there are two laws of reflection;

1. the incident ray, reflected ray, and the normal at the point of incidence all lie on the same plane.

2. angle of incidence is always equal to the angle of reflection ( i = r)

Answer 2

Answer:

The two laws of reflection are:

1. The angle of incidence is equal to the angle of reflection.
2. The incident ray, normal and the reflected ray- all lie in the same plane.

Meanings of Some terms:

1. Incident ray- The ray that falls on a mirror from a source of light.
2. Point of incidence- The point at which a ray of light touches the mirror is called the point of incidence.
3. Normal- The perpendicular to the mirror at the point of incidence is called normal.
4. Reflected ray- The ray of light that bounces back after hitting the mirror is called the reflected ray.
5. Angle of incidence- It is the angle formed between the incident ray and the normal. It is denoted by ∠i
6. Angle of Reflection- The angle formed between the normal and the reflected ray is called the angle of reflection. It is denoted by ∠r.
7. In the same plane- If you see the attached figure, the incident ray, normal and reflected ray lie in the same plane, that is the plane of the screen you are looking at.
