When light passes through a substance or gas, a part of it is absorbed and the rest scattered away. The basic process in scattering is absorption of light by the molecules followed by re-radiation in different directions. The strength of scattering can be measured by the loss of..

In order to live and enable ourselves to do everyday work we need energy. The prosperity of a country depends upon the availability of energy. Huge amount of electrical energy is used to run the air conditioners, cold storage and other domestic appliances. A large shar..

Light is a form of energy produced by luminous objects. Light can travel through vacuum. Light can penetrate through transparent materials but cannot pass through opaque objects. Light travels in a straight line in an optically homogeneou..

Judicious use of Energy - In order to live and enable ourselves to do everyday work we need energy. The prosperity of a country depends upon the availability of energy. Huge amount of electrical energy is used to run the air conditioners, cold storage and oth..
