Find the frequency of 1 `MeV` photon . Give wavelength of a 1 `KeV` photon is` 1.24 xx 10^(-9) m `

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.

A pi^(o) meson at rest decays into two photons of equal energy. If the wavelength (in m ) of the photons is 1.8xx10^(-n) then find n//2 ( The mass of the pi^(o) = 135 Me V//c^(2) )

A pi^(sigma) meson at rest decays into two photons of equal energy. If the wavelength (in m ) of the photons is 1.8xx10^(-n) then find n//2 ( The mass of the pi^(o)135 Me V//c )
