i rarely hear people say “frequency” in regards to photons, though. You say “wavelength” because it makes more sense for the context of something that is generally instantaneous.
“frequency” makes sense for things that change over time, but light almost always presents itself to us as a spatial wave, you see the wave-nature of light in diffractions and stuff as opposed to pressure waves (sound) where it obviously changes over time and is difficult to view in terms of space.
Sure, and you have radio waves and microwaves, but you also have VHF and UHF TV, ULF radio for submarines, and even radio stations are given by their frequency (even if people these days don’t think about what those numbers refer to).
