In which of the following systems will the radius of the first orbit of the electron be smallest?

In which of these, will radius of first orbit be minimum?

In which part of the electromagnetic spectrum the Lyman series of hydrogen is found ?

The allowed momenta are given by

The allowed kinetic energy of the particle is

Assume an imaginary world where angular momentum is quantized to even multiple. The longest possible wave length emitted by hydrogen in the visible spectrum is

A particle of mass $$m$$ moves around in a circular orbit in a centro symmetric potential field u(r)$$=\dfrac{kr^{2}}{2}$$. Using Bohr’s quantization rule, the permissible energy levels are 

Let $$\mathrm{v}_{1}$$ be the frequency of the series limit for Lyman series, $$\mathrm{v}_{2}$$ the frequency of the first line of the Lyman series and $$\mathrm{v}_{3}$$ the frequency of the series limit of Balmer series. Then which of the following relations is true?

The radius of hydrogen atom is 0.53 $$\mathop A\limits^0$$. The radius of $$Li^{2+}$$ is of

The difference between I and II energy levels is
