When a photon is emited by a hydrogen atom , the photon carries a momentum with it (a) calculate the momentum carreied by the photon when a hydrogen atom emits light of wavelength `656.3 nm`(b) with what speed does the atoms recoil during this transition? Take the mass of the hydrogen atom` = 1.67 xx 10^(-27) kg` (c ) Find the kinetic energy of recoil of the atom
