Light

Light is a form of energy and can be transformed into other forms of energy. You would have observed the path of 'a beam of light' inside a room. This beam is nothing but the scattered light produced by the dust particles. Beam of light becomes invisible if the room is dust free. Thus light makes things visible.Light does not require a material medium for its propagation. In a given medium light travels with a very high but finite velocity.

Reflection Of Light
When a ray of light hits a surface, it bounces off or reflects and then reaches our eyes. This 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.Or in simpler words reflection is the bouncing of light from a smooth surface. (:


When a ray of light reach the boundary between two different substances, some light is reflected, and some light is refracted. The semi-cylindrical piece of glass has a higher index of refraction than air.

SAKINAHHHHHHHHHHHHHHHHHHHHHHHHHH izme. ;D
