Q- An electromagnetic wave has a frequency of 110 MHz and is traveling in a vacuum. The magnetic field is given by B (z, t) = (2.00 x 10-8 T) cos (k z - ω t) i.
(a) Find the wavelength and the direction of propagation of this wave.
(b) Find the electric field vector E (z, t).
(c) Determine the Poynting vector.
(d) Using this Poynting vector, find the intensity of the wave.
