What is the reflection of light answer?

The reflection of light occurs whenever a ray of light falls on a smooth polished surface and bounces back. In other words, the ray of light approaching any surface results in the reflection of the light.

What is reflection of light for class 10?

Reflection of light is the phenomenon of bouncing back of light in the same medium on striking the surface of any object. The two laws of reflection are: (i) the incident ray, the reflected ray and the normal (at the point of incidence), all lie in the same plane.

What is a normal ray?

In optics, a normal ray is a ray that is incident at 90 degrees to a surface. That is, the light ray is perpendicular or normal to the surface. The angle of incidence (angle an incident light ray makes with a normal to the surface) of the normal ray is 0 degrees. In case of a normal ray, no such refraction takes place.

What is reflection give an example?

Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves.

What is the normal reflection?

An incident ray of light hits a plane mirror at an angle and is reflected back off it. The angle of reflection is equal to the angle of incidence. Both angles are measured from the normal. The normal is an imaginary line at right angles to the plane mirror.

What are the different types of reflection of light?

NOTIFICATIONS. Types of reflection. Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection. For a rough surface, reflected light rays scatter in all directions. This is called diffuse reflection.

How are the laws of reflection related to each other?

The laws of reflection determine the reflection of incident light rays on reflecting surfaces, like mirrors, smooth metal surfaces and clear water. Let’s consider a plane mirror as shown in the figure above. The law of reflection states that The incident ray, the reflected ray and the normal all lie in the same plane

How does the number of images in a reflection of light change?

The number of images we see is dependent largely on the angle between the two mirrors. We see that as we go on decreasing the angle between the mirrors, the number of images goes on increasing. And when the angle becomes zero, i.e., when the mirrors become parallel to each other, the number of images becomes infinite.

What do you call the reflection of light on a smooth surface?

This is called specular reflection. Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction.
