Question

Consider a sample of excited atoms that lie 3.077 × 10–19 J above the ground state. Determine the emission wavelength (in nanometers) of these atoms.

Answer 1

The excited electrons release photons of that energy when they relax back to ground state. To solve this you would use the same formula as in the previous question:

\(\sf E_{photon}=\dfrac{hc}{\lambda}\)
