Ahydrogen atom emits a photon that has momentum 0.3059×10^(-27) kg·m/s. this photon is emitted because the electron in the atom falls from a higher energy level into the n = 4 level. what is the quantum number of the level from which the electron falls? use values of h = 6.626×10^-34 j·s, c = 2.998×10^8 m/s, and e = 1.602×10^(-19) c.
