Beyond visible light frequencies - wave or particle?

I know that there is a debate about whether a photon is a particle or a
wave. It's easy to generate radio waves by essentially creating an
alternating electromagnet, so it seems obvious that the lower
frequencies are waves of electromagnetic radiation. When we get into
the frequencies of visible light however, it's said that photons
behave more like particles than waves. ...Or at least have properties
of both.

My question is; as you get higher and higher in the frequency spectrum,
do "waves" behave more and more like "particles"? Have
experiments been done to show that higher frequencies such as X-rays
and gamma rays behave more like particles than even photons of light?

Thanks in advance,
Mike
