Visible light consists of electromagnetic waves with wavelengths (in air) in the range 400 - 700 nm. What are the frequencies of visible light?
Since this is not my area of expertise, I searched Google under the key words "visible light frequency" to get these possible sources:
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps.
solve for frequency
where velocity is equal to speed of light.
