Before quoting the wavelength article, here is a little chart from the "Compton
Scattering" article in Wikipedia that shows how matter interacts with energy at different
energy levels. The energy levels of radiation are determined by the wavelength.

The Compton Wavelength
From Wikipedia, the free encyclopedia
Low-energy phenomena: Photoelectric effect
Mid-energy phenomena: Compton scattering
High-energy phenomena: Pair production
The Compton wavelength is a quantum mechanical property of a particle. It was
introduced by Arthur Compton in his explanation of the scattering of photons by
electrons (a process known as Compton scattering). The Compton wavelength of a
particle is equivalent to the wavelength of a photon whose energy is the same as the restmass
energy of the particle.
The Compton wavelength, λ, of a particle is given by λ = h / m c, where h is the Planck
constant, m is the particle's rest mass, and c is the speed of light. The significance of this
formula is shown in the derivation of the Compton shift formula.
The CODATA 2006 value for the Compton wavelength of the electron is
2.4263102175±33×10 −12 m. Other particles have different Compton wavelengths.
