The first three spectral lines of H-atom in the Balmer series are given by $\lambda_1,\lambda_2,\lambda_3$ respectively. Considering the Bohr atomic model, the ratio of wave lengths of first and third spectral lines $\frac {\lambda_1}{\lambda_3}$ is approximately given by $’x’ \times 10^{-1}$.

The value of x, to the nearest integer is———–. Continue reading The first three spectral lines of H-atom …. →
