10. Describe in gory detail what is meant by an electromagnetic (E-M) wave. Describe in detail the properties of an electromagnetic wave. Describe in detail the electric and magnetic fields

in an E-M wave. How do they compare to each other in magnitude and direction? What is the speed of an E-M wave, and what does this have to do with the speed of light and permittivity and permeability constants? Describe qualitatively the different parts of the electromagnetic spectrum. What is it that makes one kind of electromagnetic wave different from another kind? Describe the connection between the speed of an electromagnetic wave,its wavelength, and its frequency.
