Question
State Bohr's quantization condition of angular momentum. Calculate the shortest wavelength of the Bracket series and state to which part of the electromagnetic spectrum does it belong.
✓

Answer

Ans. According to Bohr's quantization of angular momentum, the stationary orbits are those in which angular momentum of electron is an integral multiple of $\frac{h}{2\pi}$.
$\lambda_{min}=\frac{16}{R}m$
$ = \frac{16}{1.098\times10^{7}}=14.599\times10^{-7}m$
