For the Electric field and Magnetic field given below, determine if they can be an electromagnetic wave and if they can't be an electromagnetic wave, explain why.
a) Ez = 600 sin(300900t)
By = 2 sin(300x) - 900t
b) Ez = 600 sin(30010^6 - 900t)
By = 2 * 10^-6 sin(30010^6x - 900t)
c) Ez = 600 sin(300x - 90010^6)
By = 2 * 10^-6 sin(300x - 90010^6t)
d) Ez = 600 sin(300 - 90010^6)
By = 2 sin(300x) - 900 * 10^6t
7. Write a typical EM wave for any red light with intensity 0.1 watts/m^2 traveling in the z direction. (Find Eo and Bo first from the intensity and assign a typical wavelength and frequency to red light)
