Gce Model Questions Vol1 2019 Physics Question 10
Practice objective / multiple choice question 10 from the 2019 Gce Model Questions Vol1 Physics examination.
In a hydrogen discharge tube the wavelength of the Balmer line corresponding to the transition \(n=3 \rightarrow n=2\) is measured as \(656.3\ \text{nm}\). Using this information, calculate the wavelength of the Lyman line for the transition \(n=2 \rightarrow n=1\). Use the Rydberg formula \( \frac{1}{\lambda}=R\left(\frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}}\right) \) and give your answer in nanometres to one decimal place.
