What are the values of the product of frequency and wavelength in the different spectra?

Frequency = cycles/secondWavelength = distance/cycleFrequency * Wavelength = cycles/second * distance/cycle = distance/second = speed of propagation of that type of waveFor electrometric radiation in a vacuum this will be a constant across the entire spectrum, but not when the radiation is in a material medium. For other types of waves this may be constant or vary in complex ways across the spectrum.
