Hydrogen aton in a sample are excited to `n = 5` state and it is found that photons of all possible wavelength are present in the emission spectra. The min imum number of hydrogen atom in the sample would be

Find the wavelength of electron orbiting in the first excited state of hydrogen atom.

A hydrogen atom in an excited state emits a photon which has the longest wavelength of the Paschen series. Further emissions from the atom cannot inculde the

In a hydrogen sample atoms are excited to the state with principal quantum number n. The number of different possible wavelengths emitted is

A hydrogen atom in an excited state emits a photon which has the longest wavelength of the Paschen series . Further emissions from the atom cannot include the :

Hydrogen atom is excited from ground state to another state with principal quantum number equal to 5. Then the number of spectral lines in the emission spectra will be:

A hydrogen atom ia in excited state of principal quantum number n . It emits a photon of wavelength lambda when it returnesto the ground state. The value of n is

Hydrogen atom from excited state comes to the ground state by emitting a photon of wavelength lambda . If R is the Rydberg constant, then the principal quatum number n of the excited state is

Hydrogen atom is exited from ground state to another state with principal quantum number equal to 4 Then the number of spectral linear in the emission spectra will be

The electron in hydrogen atom in a sample is in n^(th) excited state, then the number of differrent spectrum lines obtained in its emission spectrum will be

A hydrogen atom is in the third excited state. It make a transition to a different state and a photon is either obsorbed or emitted. Determine the quantum number n of the final state and the energy energy of the photon If it is a emitted with the shortest possible wavelength. b emitted with the longest possible wavelength and c absorbed with the longest possible wavelength.
