What does electromagnetic spectrum refer to?

The EM spectrum is the range of frequencies of EM radiation From low to high frequencies the spectrum goes: Radio, Microwave, Infrared, Visible, Ultraviolet, X-ray, and Gamma ray Frequency is inversely related to wavelength by c = frequency * wavelength where c is the speed of light. So the same spectrum goes from long wavelength to short wavelength.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
