The electromagnetic waves do not transport

$A$ flood light is covered with a filter that transmits red light. The electric field of the emerging beam is represented by a sinusoidal plane wave
$E_x=36\,\sin\,(1.20 \times 10^7z -3.6 \times 10^{15}\,t)\,V/m$
The average intensity of the beam will be.....$W/m^2$

$A$ source emits electromagnetic waves of frequency $8.2 \times 10^6 \text{ Hz}$. What is the wavelength of these waves in meters?

For electromagnetic waves,the electric field and the magnetic field are .......
