The frequency $\nu$ of the radiation emitted by an atom when an electron jumps from one orbit to another is given by $\nu =k∆E$, where $k$ is a constant and $∆E$ is the change in energy level due to the transition. Then, the dimension of $k$ is:

To which of the following the angular velocity of the electron in the $n^{\mathrm{th}}$ Bohr orbit is proportional?

How the linear velocity$v$ of an electron in the Bohr orbit is related to its quantum number $n ?$

If $R$ is the Rydberg constant in ${\mathrm{cm}}^{-1}$, then hydrogen atom does not emit any radiation of wavelength in the range of
