Beta particles are electrons, alphas are helium nuclei. Neither is 
electromagnetic - they are actual particles with mass, whereas photons have 
no or nearly no mass. Gamma rays, however, are high-energy enough to see 
gamma-ray photons as discrete (but nearly massless!) particles. Picture it 
as a short snippet of a wave.

Totally different thing. If you shake your hand really fast, you make very 
low frequency gravity waves that propagate through spacetime like ripples 
in a pond (I think.) They have a frequency in peaks/time, just like any 
other wave. However, it is not known whether there is such a thing as a 
graviton (which would be the coveted IVB here) or whether gravity is just a 
bending of spacetime. Ask a superstring theorist.
