What is the wavelength of an electromagnetic wave that has a frequency of 109 Hz?

Frequency * wave length = speed All electromagnetic waves travel at the speed of light. 109 * wave length = 3 * 10^8.

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.
