write about reflection of light definition and it's laws
Answers
Answer:
noun. 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.
Your Answer.
Definition :
When a ray of light falls on any object (polished, smooth, shiny object), light from that object bounces back those rays of light to our eyes and this is known as “Reflection” or “Reflection of Light”.
Laws of reflection of light:
1.The ray of light approaching the mirror is known as the incident ray
2.The ray of light that leaves the mirror is known as the reflected ray
3.At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. This line is known as a normal line .
4.The angle between the incident ray and the normal is known as the angle of incidence.
5.The angle between the reflected ray and the normal is known as the angle of reflection
