LIGHT: REFLECTION AND REFRACTION
Reflection occurs when light bounces off a surface. A highly polished surface, such as a mirror, reflects most of the light falling on it. The laws of reflection govern this phenomenon and apply to all types of reflecting surfaces, including spherical surfaces.
The fundamental laws of reflection are:
1.Angle of Incidence Equals Angle of Reflection: The angle at which the light hits a surface (angle of incidence) is equal to the angle at which it reflects off that surface (angle of reflection).
2.Incident Ray, Normal, and Reflected Ray: The incident ray (incoming light), the normal (perpendicular to the surface at the point of incidence), and the reflected ray (bounced light) all lie in the same plane.
A plane mirror reflects light to form images with specific properties:
