My TA told me that in terms of visible light, we should know the top and bottom of the range of wavelengths for visible light, and know which end corresponds to red and which corresponds to violet, but that we do not need to know, for example, exactly what is the wavelength for green and what is orange. In terms of the other types of light, I think it is important to know the order of increasing/decreasing wavelengths, but I don't think there will be any specific questions as specific as the wavelength of a microwave.

I took the test today and nothing was asked regarding the color of the wavelength; however, my t.a did mention a couple of times that you should know the range of the visible light, red=700, violet=400, as well as having a general idea of the wavelength of the other waves.
It is not required to know the exact wavelengths of the spectra but I do think it is important you know the general idea of what order the waves go in. For example you should know that infrared wavelengths are longer than visible light wavelengths and that visible light wavelengths are longer than ultraviolet wavelengths.
