The radius of innermost orbit of an electron in the hydrogen atom is $0.53\,\text{\AA}$. Then, the radius of the 3rd electron orbit is:

In Bohr's theory of hydrogen atom if speed of an electron in the first orbit is v, then the speed in 3rd orbit is

Light of wavelength \(\frac{36}{5R}\,\text{m}\) is emitted by a hydrogen atom during the transition of electrons from the state

In the hydrogen spectrum, the shortest wavelength of the Brackett series is produced during the transition:

In a hydrogen atom, the transition of an electron from the energy level, \(n_2 = \infty\) and \(n_1 = 3\) is the
