What is the frequency of radiation emitted by a photon of light if the energy released during its transition to ground state is 3.611 × 10ȹ¢ joules? (Planck's constant is 6.626 × 10È³Ê joule seconds)
I cant see the units properly. You can try using E = hf, where h is the Planck's constant and f is the frequency that you need and E is the energy released in the transition.
