What are the properties of electromagnetic radiations?

Text Solution

Verified by Experts

(a) The radiant energy is emitted from any source continuously in the form of radiations (or) waves. Radiation is the emission and transmission of energy through space in the form of waves.
(b) The electromagnetic waves consist of oscillating electric and magnetic fields. These two filed components have the same wavelengths and frequency and travel in planes perpendicular to each other and also perpendicular to the direction of propagation of electromagnetic wave.
(c) The electromagnetic waves do not require any material medium for their propagation. They can travel in vacuum also.
(d) All electromagnetic radiations travel with the same velocity, namely, with the velocity of light `(3xx 10^(8) ms^(-1))`
(e) The electromagnetic radiations consist of difterent radiations which differ in their wavelength (or frequencies) and constitue "electromagnetic spectrum". Visible light is a small portion of electromagnetic spectrum.
