Laws of Reflection

 Laws of Reflection

What we will Learn? Laws of Reflection Incident Ray Reflected Ray Normal Reflection is a principle that is characterized by a change in the path of the light through a reflecting surface. Reflection is a phenomenon whereby light ray hitting a smooth polished surface or mirror gets transferred back to the same medium. The surface that transfers the light back to the medium is called the reflecting surface. The point at which the light ray hits the reflecting surface is called the point of incidence. An imaginary line that is drawn perpendicular to the plane of reflecting surface, and the angle between the imaginary line and the angle at which the incident ray hits the reflecting surface is called that angle of incidence (i). The angle between the normal and the reflection ray is called the angle of reflection (r). There are two laws that illustrates the laws of reflection, they are 1. The angle of incidence is always equal to the angle reflection. 2. The incident ray, the normal, and the reflected ray all fall in the same plane. The light ray that hits the reflecting surface is called the incident ray and the light ray that gets reflected from the reflecting surface is called the reflected ray.
