1. Write expressions for the electric and magnetic fields of a siusoidal plane electromagnetic wae having an electric field amplitude of 300.0 V/m and a frequency of 3.00 GHz and traveling in the positive x directions.
2. Now assume we can stop the wave instantly and calculate the electric field to be
a) show that the two fields are perpendicular to each other.
b) Determine the Poynting vector for these fields.
