Waec Model Questions Vol1 2021 Physics Question 26
Practice objective / multiple choice question 26 from the 2021 Waec Model Questions Vol1 Physics examination.
A hydrogen atom is placed in a uniform magnetic field B. The normal Zeeman effect splits the Balmer‑α line (transition n = 3 \rightarrow 2, \lambda_0 = 656.3 \text{ nm}) into three components. The wavelength separation between the outermost components is measured to be 0.012 nm. Assuming the Landé g‑factor is 1, calculate the magnitude of the magnetic field B. Take \mu_B = 9.274\times10^{-24} \text{ J·T}^{-1}, h = 6.626\times10^{-34} \text{ J·s}, and c = 3.00\times10^{8} \text{ m·s}^{-1}.
