Gce Model Questions Vol1 2018 Physics Question 41
Practice objective / multiple choice question 41 from the 2018 Gce Model Questions Vol1 Physics examination.
An unknown hydrogen‑like ion (single electron) emits a photon when an electron makes a transition from the n = 4 level to the n = 2 level. The observed wavelength of this photon is 30.0 nm. Using the Rydberg formula \( \frac{1}{\lambda}=R_{\infty}Z^{2}\left(\frac{1}{n_{1}^{2}}-\frac{1}{n_{2}^{2}}\right) \) with \(R_{\infty}=1.0973\times10^{7}\,\text{m}^{-1}\), determine (i) the atomic number Z of the ion, and (ii) the wavelength of the photon emitted when the electron transitions from n = 3 to n = 1.
