Problem: The components of the electric field in an electromagnetic wave traveling in vacuum are described by Ex = 0, Ey = 0, and Ez = 5.68 sin(8.74x - ?t) V/m, where x is measured in meters and t in seconds.
Part A: Calculate the frequency of the wave.
Part B: Calculate the wavelength of the wave.
Part C: Calculate the amplitude of the magnetic field of the wave.
Part D: Calculate the intensity of the wave.
Show each step in detail for help.
