Question

For hydrogen atom, &#955; 1 and &#955; 2 are the wavelengths corresponding to the transitions 1 and 2 respectively as shown in figure. The ratio of &#955; 1 and &#955; 2 is x 32 . The value of x is ______.

Wavelength corresponding to the photon emitted in transition $n = 3 t o n = 1$ is

$\frac{1}{λ_{1}} = R (\frac{1}{1^{2}} - \frac{1}{3^{2}}) = \frac{8 R}{9}$ ....(1)

Wavelength corresponding to the photon emitted for transition in transition $n = 2 t o n = 1$ is

$\frac{1}{λ_{2}} = R (\frac{1}{1^{2}} - \frac{1}{2^{2}}) = \frac{3 R}{4}$ ....(2)

$\frac{λ_{1}}{λ_{2}} = \frac{3 R}{4} \times \frac{9}{8 R} = \frac{27}{32}$

Hence, the value of $x = 27$ .
