Q23 (b)

Development of models of the atom has resulted from both experimental investigations and hypotheses based on theoretical considerations.
Explain how de Broglie’s hypothesis regarding the nature of electrons addressed limitations in the Bohr–Rutherford model of the atom.

Q24 (b)

An absorption spectrum resulting from the passage of visible light from a star’s surface through its hydrogen atmosphere is shown. Absorption lines are labelled W to Z in the diagram.

Absorption line WWW originates from an electron transition between the second and sixth energy levels. Use

1λ=R(1nf2−1ni2)\frac{1}{\lambda} = R\left(\frac{1}{n_f^2} - \frac{1}{n_i^2}\right)λ1​=R(nf2​1​−ni

to calculate the frequency of light absorbed to produce absorption line WWW.
