State 2 laws of reflection?
The 2 laws of reflection are 1. angle of incidence is always equal to the angle of reflection. And 2. incident ray,reflected ray and the normal at the point of incidence lie in the same plane.
What are the laws of a reflection?
The laws of reflection state that the angle of incidence is equal to the angle of reflection, the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.
How many laws of reflection?
There are three laws of reflection and which 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.The reflected ray and the incident ray are on the opposite sides of the normal.
What are rule of reflection?
The rules of reflection state that the incident angle is equal to the reflected angle, the incident ray, the normal to the surface, and the reflected ray all lie in the same plane, and the angle of incidence is equal to the angle of reflection.
An activity to show that the incident ray the reflected ray and the normal at the point of icident ray lie in the same plane?
Place a plane mirror on the table. Take a paper sheet and make a small hole in its centre. Make sure that the light in the room is not bright. Hold the sheet normal to the table. Take another sheet and place it on the table in contact with the vertical mirror. Draw a normal line on the second sheet from the mirror. Now, light a torch on the mirror through the small hole such that the ray of light falls on the normal at the bottom of the mirror. When the ray from this hole is incident on the mirror, it gets reflected in a certain direction. You can easily observe the incident ray, reflected ray and the normal to the mirror at the point of incidence on the sheet placed on the table. This shows that the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.

What are law of reflection?
1. The angle of incidence is equal to the angle of reflection. 2. The reflected ray, the incident ray and the normal at the point of incidence lie on the same plane.
What is stated in the law of reflection?
1.The angle of incidence is equal to the angle of reflection. 2.The incident ray, the reflected ray and the normal ,all lie in the same plane
State the law of refraction?
Ans. The law of reflection states for that: 1. The angle of incidence is equal to the angle of reflection. 2. The incident ray, the reflected ray, and the normal at the point of incidence lie in the same plane.
What are the two laws of reflection?

An activity to show that the incident ray the reflected ray and the normal at the point of icident ray lie in the same plane?

Take another sheet and place it on the table in contact with the vertical mirror. Draw a normal line on the second sheet from the mirror.

When the ray from this hole is incident on the mirror, it gets reflected in a certain direction. You can easily observe the incident ray, reflected ray and the normal to the mirror at the point of incidence on the sheet placed on the table. This shows that the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.
What is reflecting mirrors?
When a light ray is incident upon a reflecting surface, the angle of reflection is equal to the angle of incidence. Both of these angles are measured relative to a normal drawn to the surface. The incident ray, the reflected ray, and the normal all lie in the same plane.
According to the law of reflection which two angles must be equal?
According to the law of reflection, the angle of incidence (the angle between the incident ray and the normal line) must be equal to the angle of reflection (the angle between the reflected ray and the normal line) when a ray of light reflects off a surface.
