Igcse Model Questions Vol1 2019 Physics Question 20
Practice objective / multiple choice question 20 from the 2019 Igcse Model Questions Vol1 Physics examination.
An electron in a hydrogen atom drops from the \(n=5\) level to the \(n=2\) level, emitting a photon. It then absorbs a photon and is excited to the \(n=4\) level. Using the Rydberg constant \(R = 1.097\times10^{7}\ \text{m}^{-1}\), calculate the wavelength of the absorbed photon in nanometres. Give your answer to three significant figures.
