Igcse Model Questions Vol1 2020 Physics Question 29
Practice objective / multiple choice question 29 from the 2020 Igcse Model Questions Vol1 Physics examination.
For a hydrogen‑like ion with atomic number \(Z = 3\) (the Li\(^{2+}\) ion), use the Bohr model to find the wavelength of the photon emitted when an electron makes a transition from the \(n = 5\) level to the \(n = 2\) level. Compare the calculated wavelength with an observed spectral line at \(102.6\,\text{nm}\) and state whether they match. (Take the Rydberg energy \(13.6\,\text{eV}\) and \(hc = 1240\,\text{eV·nm}\).)
