Gaseous calcium atoms absorb light at 423, 272, and 240 nm.After a photon of 272 nm is absorbed from the ground state, aphoton of wavelength 672 nm is emitted. After absorption of aphoton of 240 nm occurs from the ground state, a photon is emittedof wavelength 504 nm.
1. After the 504 nm photoemission occurs, what wavelength oflight (in nm) would have to be emitted for an electron to return tothe ground state? Construct an energy diagram to help.
2. What is the energy difference between the second highest andthird highest states? Construct an energy diagram to help.
