Question

introduction of reflection of light​

Answer 1

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.

Answer 2

Answer:

What is Reflection of Light?

When a ray of light approaches a smooth polished surface and the light ray bounces back, it is called the reflection of light. The incident light ray which lands upon the surface is said to be reflected off the surface. The ray that bounces back is called the reflected ray. If a perpendicular were to be drawn on a reflecting surface, it would be called normal. The figure below shows the reflection of an incident beam on a plane mirror.

Here, the angle of incidence and angle of reflection are with respect to the normal and the reflective surface.

LAWS OF REFLECTION:-

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

The angle of incidence = Angle of reflection
