Complex sentence: However, if gravitons are the quanta of gravitational waves, then the relation between wavelength and corresponding particle energy is fundamentally different for gravitons than for photons, since the Compton wavelength of the graviton is not equal to the gravitational wave wavelength.
Split into simpler sentences: However, if gravitons are the quanta of gravitational waves, then the relation between wavelength and corresponding particle energy is fundamentally different for gravitons than for photons. The Compton wavelength of the graviton is not equal to the gravitational wave wavelength.
