The angle between the incident ray and the normal is known to be angle of incidence
The angle between the reflected ray and the normal is said to be angle of reflection
By the law, the angle of incidence = angle of reflection
The angle between the incident ray and the normal is known to be angle of incidence The angle between the reflected ray and the normal is said to be angle of reflection By the law, the angle of incidence = angle of reflection
The relation between the incident ray and reflected ray is described by the material which is reflecting the incident ray. depending upon the material used the incident ray is scattered or reflected or refracted or transmitted or absorbed. For example if you take rainbow the sun light is incident on the rain drop , it reflected back of drop several times and due to that we get the rainbow with various colours.
The angle between the incident ray and the reflected ray is equal to the angle between the incident ray and the normal. When the mirror is rotated, the normal also rotates by the same angle. Therefore, the angle between the incident ray and the reflected ray will still be 20 degrees.
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.
The normal to the reflecting surface.
Call the angle from the incident ray to the normal X. The angle of the reflected ray to the normal also has to be X because the incidence angle and the reflected angle are equal by law of reflection. Since the angle between the reflected and incident ray is 90 degrees: 2*X = 90 So, X = 45 degrees.
The line perpendicular to a reflecting surface where the incident ray ends and the reflected ray begins is called the normal line.
The normal line divides the angle between the incident ray and the reflected ray into two equal angles.
incident ray-the light ray striking a reflecting surface is called the incident ray. reflected ray-the light ray obtained after reflection from the surface, in the same medium in which the incident ray is travelling , is called the reflected ray.
The plane at which the incident ray, the reflected ray, and the normal lie is known as the plane of reflection. This plane is perpendicular to the surface of the reflecting object and contains all three of these elements.
An incident ray is the ray of light that approaches a surface, while a reflected ray is the ray of light that bounces off the surface after striking it. The angle of incidence of the incident ray is equal to the angle of reflection of the reflected ray, as per the law of reflection.
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.
