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.
