Direction found by law of reflection
WebThe law of reflection only holds if the collision is elastic and the object which the ball collides with does not move. If the collision is not elastic then the perpendicular component of velocity is smaller after than before, whereas the parallel component is the same.

WebApr 7, 2024 · The angle of reflection in the law of light - When an angle is a result of the reflected ray and the normal ray, it is known as the angle of reflection. Normal - Whenever a line makes an angle of 90 degrees, i.e., a straight line angle of the mirror, at any point where the incident ray is supposed to strike the mirror is known as the normal.

WebThe Law of Reflection 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.
