List of top Physics Questions on Bohr's model of hydrogen atom asked in UP Board XII

The difference in angular momentum of electron between two successive orbits of hydrogen atom is
What is the meaning of stationary orbit of atom? Deriving formula for the energy of the electron in the stationary orbit of the hydrogen atom, mention its relation with the radius of the orbit of electron.
Energy of electron in the \(n\)th orbit of hydrogen atom is \( E_n = \frac{-13.6}{n^2} \, \text{eV} \). Draw the energy level diagram for hydrogen atom and show the transition for lines of Balmer and Paschen series.
If the circumference of the nth orbit of an electron is \(S\) and the corresponding de Broglie wavelength of the orbit is \(\lambda\), then on the basis of Bohr's atom model, prove that \(S = n\lambda\).
In hydrogen atom, the kinetic energy of electron in an orbit of radius \( r \), is given by:
Draw energy level diagram for hydrogen atom. Show the transitions of the first line of Lyman series and second line of Balmer series. Find out the ratio of their wavelengths.
Hydrogen atom in its ground energy state absorbs a photon, which excites it to an energy level of \(n = 4\). Calculate the frequency of photon.
Write down Bohr's postulates for hydrogen atom. Prove that orbital radius (r) of hydrogen atom is directly proportional to square of the principal quantum number (n).
The energy of electron in an excited hydrogen atom is -3.4 eV. Determine the angular momentum of this electron.
