when a photon is emmited from an atom ,the atom recoils .the kinetic energy of recoil and the energy of the photon come from the difference in energies between the states innvolved in the transition.suppose a hydrogen atom changes state from n=2 to n= 3 ..................calculate the fractional change in the wavelenght of the light emitted due to recoil
