what are the laws of reflection of light....?its urgent
Answers
When a ray of light strikes a plane mirror, the light ray reflects off the mirror. Reflection involves a change in direction of the light ray. The convention used to express the direction of a light ray is to indicate the angle which the light ray makes with a normal line drawn to the surface of the mirror. The angle of incidence is the angle between this normal line and the incident ray; the angle of reflection is the angle between this normal line and the reflected ray. According to the law of reflection, the angle of incidence equals the angle of reflection. These concepts are illustrated in the animation below.
The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane.
Furthermore, the angle of reflection is equal to the angle of incidence, This type of reflection is called diffuse reflection, and is what enables us to see non-shiny objects.
