Assuming that the smallest measurable wavelength in an experiment is 0.570 fm , what is the maximum mass of an object traveling at 745 m ⋅ s-1 for which the de Broglie wavelength is observable?
When an excited electron in a hydrogen atom falls from n=7n to n=2, a photon of ultraviolet light is emitted. If an excited electron in an He+ ion falls from n=5, which energy level must it fall to (n1) for ultraviolet light of a similar wavelength to be emitted?
