Neco 2022 Physics Question 25
Practice objective / multiple choice question 25 from the 2022 Neco Physics examination.
An electron in a hydrogen atom drops from the third to the first energy level, emitting a photon. The photon is absorbed by another hydrogen atom, exciting its electron from the ground state (n=1) to the third level (n=3). The excited electron then returns to the ground state via the intermediate level n=2, emitting a photon in the first step (n=3 \(\rightarrow\) n=2). Determine the wavelength of this photon in nanometres, correct to two decimal places.
