A ground state hydrogen atom absorbs a photon of wavelength 94.98 nm and its electron attains a higher energy level. The atom then emits two photons: one of wavelength 434.2 nm to reach an intermediate level and a second to return to the ground state. What was the wavelength of the second photon emitted?
