Neco Model Questions Vol1 2017 Physics Question 44
Practice objective / multiple choice question 44 from the 2017 Neco Model Questions Vol1 Physics examination.
A hydrogen atom is initially in the \(n=3\) energy level. It absorbs a photon and is excited to the \(n=5\) level. The atom can then return to the ground state (\(n=1\)) either by emitting a single photon directly (transition \(5\rightarrow1\)) or by emitting two photons in succession (\(5\rightarrow3\) followed by \(3\rightarrow1\)). Calculate the ratio \(\displaystyle \frac{\lambda_{5\rightarrow1}}{\lambda_{5\rightarrow3}+\lambda_{3\rightarrow1}}\), where \(\lambda\) denotes the wavelength of the emitted photon for each transition. Give your answer to three significant figures.
