A proton is located at a distance of 0.420 m from a point charge of +8.30 micro coulombs. The repulsive electric force moves the proton until it is at a distance of 1.58 m from the charge. Assume that the electric potential energy lost with the system is carried off by a photon that is emitted during the process. What is its wavelength?
