Frequency = Wavelength- the Test

-
Some years ago I was having a discussion with olegt about greenhouse gases. We were both presenting papers on the subject, some were discussed the frequency of the emissions while other discussed the wavelengths. Regardless of frequency or wavelength the papers were discussing the same emission spectrum. The same EM waves. Ie frequency = wavelength, in that context.

Enter evoTARDs looking for something to drool over, misrepresent- for YEARs- and ignore all attempts to walk them through it as you would a 4 year old.

So, with that in mind, I ask:


Can any wave be referred to by its frequency or equivalently by its wavelength? For example if one person is talking about CO2’s emissions by their frequencies and another person is using their wavelengths, are those two people talking about the exact same thing?
