If the electron in the hydrogen atom jumps from the third orbit to the second orbit, the wavelength of the emitted radiation in term of Rydberg constant is

Options:

Answer:

Solution:

$\frac{1}{λ} = R (\frac{1}{2^{2}} - \frac{1}{3^{2}})$

$= R (\frac{1}{4} - \frac{1}{9})$

$\frac{1}{λ} = R (\frac{9 - 4}{36})$

$= \frac{5 R}{36}$

$λ = \frac{36}{5 R}$
