If $r$ and $v$ represent, respectively, the orbital radius and orbital velocity of the electron in the Bohr's theory of hydrogen atom, then they are proportional to the orbit number as
In a hydrogen atom, the radius of the $n^{th}$ Bohr orbit is proportional to
The number of de Broglie waves associated with Bohr electron when it completes one revolution in its third orbit is
The ratio of the velocities of the electron in the second, third and fourth Bohr’s orbits of the hydrogen atom is:

For the hydrogen spectrum,the wavelength in Balmer series is given by \(\frac{1}{λ}\)=R(\(\frac{1}{n_{1}^{2}}\)-\(\frac{1}{n_{2}^{2}}\)) where λ= wavelength and R is Rydberg constant. What are the values of n1 and n2,for the longest wavelength in the Balmer series?

In Bohr atom model, the total energy of the electron in hydrogen atom is -3.4eV. Then its angular momentum about the nucleus of the atom is (h=Planck's constant)
