If the electron in hydrogen atom jumps from third orbit to second orbit, the wavelength of the emitted radiation is given by:

Options:

Answer:

Solution:

We have, $\frac{1}{λ} = R (\frac{1}{n _{1}^{2}} - \frac{1}{n _{2}^{2}})$ $\frac{1}{λ} = R (\frac{1}{2 ^{2}} - \frac{1}{3 ^{2}}) \frac{1}{λ} = R (\frac{1}{4} - \frac{1}{9}) \frac{1}{λ} = R (\frac{9 - 4}{36}) \frac{1}{λ} = R \times \frac{5}{36} λ = \frac{36}{5 R}$
