Check out the De Brogli wavelength: http://calistry.org/calculate/deBroglieEquation Ordinary particles have a wavelength so small that we can't see the oscillations (this is because ordinary particles have mass). An FM radio station transmitting at 100 MHz emits photons with an energy of about 4.1357 × 10 eV. This minuscule amount of energy is approximately 8 × 10 times the electron's mass (via mass-energy equivalence). Very-high-energy gamma rays have photon energies of 100 GeV to over 1 PeV (10 to 10 electronvolts) or 16 nanojoules to 160 microjoules.
