light reflection and refraction

Reflection of Light - It is the phenomenon of change in the path of light without any change in mediu..

The figure shows how a ray of light is reflected by a plane surface. Let MM' represent a reflecting surface. When a ray of light is incident on MM' in the direction IO it gets reflected along the direction OR. IO is the incident ray; O is the point..

The incident ray, the reflected ray and the normal at the point of incidence all lie in the same plan..

Introduction - It is a matter of common experience that the objects inside a dark room, which are invisible, become visible when the room is illuminated by a source of light. Thus light can be defined as the external cause responsible for the sensation of vision. The branch of P..

Total Internal Reflection - Let us consider a ray of light passing from glass to air, that is from a denser medium to a rarer medium. The figure shows that for a small angle of incidence, major part of the incident light is refracted and a small portion is ..

A ray of light incident normally to XY goes undeviated along AB. As the angle of incidence increases, the angle of refraction also increase..

A ray of light refracts or deviates from its original path as it passes from one optical medium to another because the speed of light change..

Atmospheric refraction is the shift in apparent direction of a celestial object caused by the refraction of light rays as they pass through Earths atmospher..
