Question

The electric and magnetic field of an electromagnetic wave are in(a) phase and parallel to each other(b) opposite phase and perpendicular to each other(c) opposite phase and parallel to each other(d) phase and perpendicular to each other

Answer 1

Answer:

D) phase and perpendicular to each other

Explanation:

Electromagnetic waves are the waves carrying sinusoidal variation of electric and magnetic field vectors. The variations are carried at both the right angles to each other as well as to the direction of wave propagation.

Sinusoidal variation = E→B→ ( simultaneously)

Thus, as a result they attain the minima and maxima at the same place and at the same time. The electromagnetic waves, electric and magnetic field are in phase and perpendicular to each other and also perpendicular to the direction of the propagation of the wave.
