Q)

A plane sinusoidal linearly polarized electromagnetic wave of wavelength 5×107m travels in vacuum in the direction of x - axis. The average intensity of the wave per unit area is 0.1W/m2 and the plane of vibration of electric field is parallel to y - axis. The equations describing the electric and magnetic field of this wave is

(a)Ey=2.9×109N/msin(4π×106)(tx/c)(b)Ey=8.67N/msin(2π×106)(tx/c)(c)Ey=8.67N/msin(4π×106)(tx/c)(d)Ey=2.9N/msin(2π×106)(tx/c)
