Although a hydrogen atom has only one electron, the hydrogen atom possesses a complete set of available orbitals. What purpose do these additional orbitals serve?

An atom emits yellow light when an electron makes the transition from the n = 5 to the n = 1 level. In separate experiments, suppose you bombarded the n = 1 level of this atom with red light, yellow light (obtained from the previous emission), and blue light. In which experiment or experiments would the electron be promoted to the n = 5 level?

III. As the wavelength of light increases, its frequency increases. a I only b II only c III only d I and III only e II and III only
