Question

E and B represent the electric and the magnetic field of an electromagnetic wave respectively. The direction of propagation of the wave is along

The electric field of an electromagnetic wave passing through vacuum is represented as Ex = E₀ sin (kz − ωt). Identify the parameter which is related to the (i) wavelength, and (ii) the frequency of the wave in the above equation.

Write two properties of a medium that determine the velocity of light in that medium.

Depict a plane electromagnetic wave propagating along the x-axis. Write the expressions for its oscillating electric and magnetic fields.
