a) electromagnetic wave are transverse in nature whise speed is same as that speed of light.
b) the two field B and E have same frequency of oscillation and they are in same phas with each other.
c)the electric field responsible for the optical effects of an electromagnetic wave and is called the light vector.
d) E and B are such that ExB (is always in the direction of propagation of wave .
e) electromagnetic wave obey the superposition principle because the differencial equations involving E and B are linear equations .i.e. we can add two waves with the same frequency simply by adding the magnitude of the two electric field algebrically.
f) electromagnetic wave shows the properties of refraction, reflection, interference, diffraction and polarisation.
