Question

Bohr model of an atom could not account for

1) emission spectrum

2) absorption spectrum

3) line spectrum of hydrogen

4) fine spectrum

Answer 1

Answer: 4): fine spectrum.

Bohr’s model was successful in explaining the spectra of the hydrogen atom and hydrogen-like systems such as $H^{1+},L{i}^{2+}$, etc., it could not account for the fine structure in the spectrum observed using refined spectroscopic techniques.
