A plain electromagnetic wave travels in vacuum along the Y-direction. Write the the directions of its electric and magnetic field vectors.

Express the velocity of propagation of an electromagnetic wave in terms of the peak values of the electric and magnetic fields.

Electromagnetic waves Electromagnetic waves are those waves in which there are sinusoidal variations of electric and magnetic fields at right angle to each other as well as right angle to the direction of propagation. The ratio of electric vector and magnetic vector gives the velocity of light and vecExxvecB gives the direction of propagation of electromagnetic wave. The electric and magnetic field of an electromagnetic wave are
