Properties of Electromagnetic Waves
Electromagnetic waves are produced by accelerated charges.
PROPERTIES OF ELECTROMAGNETIC WAVES (i) Electromagnetic waves are produced by accelerated charges. (ii) They do not require any material medium for propagation. (iii) In an electromagnetic wave, the electric (iv) Variation of maxima and minima in both (v) They travel in vacuum or free space with a speed 3 × 108 ms-1 given by the relation c = (μ0 - permeability of free space and ε0 - permittivity of free space) (vi) The energy in an electromagnetic wave is equally divided between electric and magnetic field vectors. (vii) The electromagnetic waves being chargeless, they are not deflected by electric and magnetic fields.
and magnetic 
field vectors are at right angles to each other and to the direction of propagation. Hence, electromagnetic waves are transverse in nature.
