# How well did you verify the law of reflection

## How do you verify the law of reflection?

Verification of the Laws of Reflection

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

## Is the law of reflection always true?

Law of Reflection

One thing is true of both regular and diffuse reflection. The angle at which the reflected rays leave the surface is equal to the angle at which the incident rays strike the surface. … According to the law of reflection, the angle of reflection always equals the angle of incidence.

## What are the 3 laws of reflection?

The laws of reflection are as follows: The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane. The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.

## What are the 2 laws of reflection?

The two laws of reflection are as follows: … The incidenct ray, the reflected ray, and the normal to the reflecting interface at the point of incidence all lie in the same plane. 2. The angle of incidence equals the angle of reflection.

## What is the law of reflection?

The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.

## How do you prove the angle of incidence is equal to the angle of reflection?

Answer. whenever a ray of light i.e. the incident will hit a point at plane mirror i.e. the normal then the ray of light will get reflected back in the same way i.e. the reflected ray. both rays form an angle on the normal i.e. the angle of incidence and angle of reflection.

## How will you prove the first law of reflection of light with the help of a ray box?

The incident ray, the reflected ray and the normal all lie in the same plane. Furthermore, it states that the angle of incidence is equal to the angle of reflection. i.e. θi = θr. … Therefore according to the first law of reflection.

## Why is the law of reflection true?

For rough surfaces, the law of reflection remains valid. … It predicts that rays incident at slightly different points on the surface are reflected in completely different directions, because the normal to a rough surface varies in direction very strongly from point to point on the surface.

## What is the incident ray?

An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence. The reflected ray corresponding to a given incident ray, is the ray that represents the light reflected by the surface.

## Does a rough surface reflect light?

If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. … For a rough surface, reflected light rays scatter in all directions. This is called diffuse reflection.
