what is reflection ?
Answers
Answer:
Here's Your Answer
Explanation:
The process of sending back light rays which fall on the surface of an object, is called reflection of light. A plane mirror reflects almost all the light which falls on it. In order to study the reflection of light, we need an apparatus which can produce a thin beam of light.

Explanation:
◆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.
Law
This is called the law of reflection. So, if a wave hits a mirror at an angle of 36°, it will be reflected at the same angle (36°). ... 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.
Types
The reflection of light can be roughly categorized into two types of reflection. Specular reflection is defined as light reflected from a smooth surface at a definite angle, whereas diffuse reflection is produced by rough surfaces that tend to reflect light in all directions
