If λ= 9.7xx10^-8m , what is frequency of photon ?

A 20 KeV energy electron is brought to rest in an X-ray tube, by undergoing two successive bremsstrahling events, thus emitting two photons. The wavelength of the second photon is 130 xx10^(-12) m greater than the wavelength of the first emitted photon. Calculate the wavelength of the two photons.

If wavelength of photon is 2.2× 10 ^(−9) m, h=6.6× 10 ^(−34) Jsec, then momentum of photon is
