In photons of energy 12.75 eV are passing through hydrogen gas in ground state then no. of lines in emission spectrum will be

In photons of energy 12.75 eV are passing through hydrogen gas in ground state then no. of lines in emission spectrum will be

A photon of energy 10.5eV is allowed to interact with a hydrogen atom in its ground state. Then :

Atomic hydrogen is excited from the grounds state to the n^(th) state. The number of lines in the emission spectrum will be:

Atomic hydrogen is excited from the grounds state to the n^(th) state. The number of lines in the emission spectrum will be:

In a sample of hydrogen like atoms all of which are in ground state, a photon beam containing photos of various energies is passed. In absorption spectrum, five dark line are observed. The number of bright lines in the emission spectrum will be (assume that all transitions take place)
