: Yes light speed is the speed of visable light : as the higher frequencys of light have a limited : range that they can travel a good example : is the way in which light diffuses underwater : and in the atmosphere also radio waves if you : broadcast at a high megahertz admitidly you : have a very powerful radio but the lower : the freq but greater the volume or energy the longer : the signal lasts : don't know if that made much sense but hope : irt helps

No, speed of light is the constant for all frequences. It is not constant for all mediums but about the same for our perceptions. All the different waves you mentioned like gamma, x-ray, visible radio, etc. are just names for different frequencies. c = wavelength * frequency Range limitations is attenuation and dissipation effect. the same uniform medium can not create different frequencies (else the medium is nonlinear transfer function - near strong gravity).
