what is reflection and it's law
Answers
Explanation:
the principle that when a ray of light, radar pulse, or the like, is reflected from a smooth surface the angle of reflection is equal to the angle of incidence, and the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane
Reflection is the change in direction of a wave at a boundary between two different media, so that the wave moves back into the medium it came from. The most common examples include the reflection of light, sound and water waves.
The laws of reflection 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.
