electromagnetic radiation spectrum

While all electromagnetic waves travel at the same speed (i.e., velocity 'c' is constant), the type of their radiation differs in the duration of wavelength and consequently their frequencies. An electromagnetic radiation with a long wavelength will have a..

Sun is the ultimate source of energy for organisms either directly or indirectly solar radiation before entering the atmosphere carries energy at a constant rate of 2 cal cm - 2 min - 1 , which is known as the solar constant. Solar spectrum is made up of short wave radi..

In 1900, Max Planck presented the results of his famous black body radiation experiments, which showed that light has a dual character, behaving like a particle as well as a wave. He gave the Quantum Theory of Radiation explaining electromagnetic radiation..

-rays. Similarly, if the radiations given out by a radioactive substance are subjected to an electric field perpendicular to their path, they separate into three constituents. Those which turn towards the negative plate are the positively charged alpha particles. Those, which turn toward..

Electromagnetic Nature of Light - In 1856, James Clark Maxwell proposed that light and other forms of radiant energy propagate themselves in the form of waves, through space. These waves have electric and magnetic fields associated with them and are called electromagnetic waves ..

Electromagnetic waves Matter waves Electromagnetic are associated with electric and magnetic fields perpendicular to each other and to the direction of propagation of radiation Matter waves may not be associated with electric and magnetic fields h..

The solar spectrum of electromagnetic waves include energy packed heat generating waves called radiation waves. As they lie beyond red colour waves of visible spectrum, they are also called 'infra-red rays'. These infrared rays lie in the wave length ra..
