light-reflection and refraction

A prism is a portion of a transparent medium bounded by two plane faces inclined to each other at a suitable angle. ..

Let us now perform an experiment and find out how light gets refracted when it is incident on a rectangular glass slab. Place a rectangular glass slab on a white sheet of paper fixed on a drawing board. Trace the boundary ABCD of the glass slab. Remove the glass slab. D..

Introduction - when a ray of light travelling in one medium enters another medium of different optical densit..

The phenomenon by which a ray of light changes the direction of propagation when it strikes a boundary between different media through which it cannot pass is described as the reflection of light..

Summary - Light is a form of energy which can be reflected either by a plane or spherical mirror. Depending upon the type of mirror used for reflection of light the use of reflecting surface also varies. In the next chapter let us see what happens w..

Reflection of Light by a Plane Surface - 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 al..

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 ..
