we have discovered from radio waves to gamma rays but there may possibilites of existence of other electromagnetic waves beyond this range which we haven't discovered it, may be the reason that our current technology not have that "EYE" to see those waves. Is there any possibility of such waves having more frequency than gamma rays and wavelength than radio waves.
