Solve the all parts of given problem:
Problem: A traveling sinusoidal electromagnetic wave in vacuum has an electric field amplitude of 62.1 V/m.
Part A: Find the intensity of this wave?
Part B: Calculate the energy flowing during 10.7 s through an area of 0.0211 m2 that is perpendicular to the wave\'s direction of propagation?
Please explain how you came to your conclusion for above problem.
