According to Bohr theory only those orbit are allowed along which angular momentum of electron is:
Correct answer: B. nh/2π
- A. 2π/nh
- B. nh/2π
- C. n/2πh
- D. 2πn/h
Explanation
In Bohr's theory, only certain electron orbits are allowed where the angular momentum of the electron is quantized, meaning it can only have specific values. The angular momentum is quantized as n times h over 2π, where n is a positive integer representing the energy level of the electron. This quantization of angular momentum was a key aspect of Bohr's model in explaining the stability of the electron orbits in an atom. It's like the electron can only dance in certain designated circles around the nucleus!

About Spectrum of Hydrogen
The hydrogen spectrum consists of discrete emission lines produced when electrons fall between quantised energy levels and release photons. Questions use the Rydberg equation, photon energy and wavelength, and identify the Lyman, Balmer, Paschen, Brackett and Pfund series, which differ from continuous spectra.
