What is emission spectrum ?

Assertion: Hydrogen atom consists of anly one electron but its emission spectrum has may lines. Reason: Only Lyman series is found in the absorption spectrum of hydrogen atom whereas in the emission spectrum, all the series are found.

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

The ratio of longest wavelength and the shortest wavelength observed in the 5 spectral series of emission spectrum of hydrogen is .......

What is a spectrum ?

An electron in hydrogen atom after absorbing-an energy photon jumps from energy state n_(1) to n_(2) . Then it returns to ground state after emitting six different wavelengths in emission spectrum.'The energy of emitted photons is either equal to, less than or grater than the absorbed photons: Then n_(1) and n_(2) are:

What is hydrogen spectrum give its characteristic ?

Explain emission line spectra and absorption spectra.

A sample of hydrogen gas is excited by means of a monochromatic radiation. In the subsequent emission spectrum, 10 differenet wavelengths are obtained, all of which have enrgies greater than or equal to the energy of the abosrbed radiation. Find the intitial quantum number of the state (before abosrbing radiation).
