Why can the spectral lines of hydrogen atom not be explained by Rutherford's atomic model ?

State two limitations of Rutherford's atom model.

In hydrogen atom spectrum

In Bohr's model of hydrogen atom ,

What is the ratio of frequencies of the spectral lines of hydrogen atom for transition form 4 to 1 and 4 to 2 ?

In which part of the electromagnetic spectrum do the spectral lines of hydrogen atom as given by Balmer series occur?

What is the approximate diameter of a hydrogen atom ?

Explain the origin of spectral lines of hydrogen from Bohr's postulates.

The value of Bohr radius for hydrogen atom is

The longest wavelength transitoin in one of the spectral series of hydrogen atom is 6563 Å. Identify the series to which the spectral line belongs.
