Of the following transitions in hydrogen atom, the one which gives an absorption line of lowest frequency is
Of the following transitions in hydrogen atom, the one which gives an absorption line of lowest frequency is
$\mathrm{n}=1$ to $\mathrm{n}=2$
$\mathrm{n}=3$ to $\mathrm{n}=8$
$\mathrm{n}=2$ to $\mathrm{n}=1$
$\mathrm{n}=8$ to $\mathrm{n}=3$
Solution
Absorption line in the spectra arise when energy is absorbed i.e., electron shifts from lower to higher orbit, out of a and $b, b$ will have the lowest frequency as this falls in the Paschen series
