The kinetic energy of a massive particle is equal to the energy of a photon.  The massive particle moves at 1.49 % the speed of light.  
What is the ratio of the photon wavelength to the de Broglie wavelength of the particle?  (Assume the standard nonrelativistic expressions for the momentum and kinetic energy of the massive particle.)
