how are the energy and wavelength of electromagnetic radiation related

where 'h' is proportionality constant, universally referred to as Planck's constant. It has a fixed value of: h = 6.63 x 10 3 4 joule.sec or h = 3.99 x 10 - 1 3 kJ sec mol - 1 . This relation was found to be valid for all types of electromagnetic radiation. The total a..

The third mode of energy transfer between an object and its environment is via electromagnetic waves (visible light is a kind of electromagnetic wave). Energy transferred in this way is often called thermal radiation, to distinguish it from ele..

They do not require any medium for propagation; in other words, these waves can pass through vacuum They require medium for propagation i.e. these waves cannot pass through vacuum All electromagnetic waves travel with the same velocity Matter waves travel with different veloc..

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 wavelen..

Similar to the crystal diffraction patterns produced by X-rays, even the beam of electrons of appropriate momentum could produce crystal diffraction pattern. Imparting the desired momentum to the electron obtained by thermionic emission from a heated filament was done by electrostatic acceleration...

. have also dual character. In other words, the microscopic particles in motion possess both the particle and wave characteristics. Thus, according to de-Broglie, "all material particles in motion possess wave characteristics". According to de-Broglie, the wavelength associated with a par..

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 or electromagnetic..

Albert Einstein, in the beginning of this century, showed that matter (whatever the form) was equivalent to energy. The energy associated with a mass 'm' (just because of its existence) is given by the famous formula of Einstein, E = mc 2 ------------ (1). where 'c' is the spe..
