: : 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).
