Define reflection and Explain two laws of reflection.
Answers
→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.
→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.
The law of reflection states that when a ray of light reflects of a surface then angle of incidence is equal to the angle of reflection
Explanation:
First law states that angle of incidence=angle of reflection.
second law states that incidenct ray, reflected ray and normal all lie on same plane
