When white radiation is passed through a sample of hydrogen gas at room temperature , absorption lines are observed in lyman series only Explain

A parallel beam of light of wavelength 100 nm passes through a sample of atomic hydrogengas in ground state (a)Assume that when a photon suppose some of its energy to a hydrogen atom the rest of the energy appears as another photon moving in the same direction as the incident photon Neglecting the light emitted by the excited hydrogen ato in the direction of the incident beam, ? (b) A radiation detector is placed near the gas to detect radiation coming perpenducular to the incident beam find the wevelength of radiation that may be detected by the detector

A beam of light having wavelength distributed uniformly between 450 nmto 550 nm passes through a sample of hydrogen gas which wavelength will have the least intensity in the transition beam?

When a vapour is excited at low pressure by passing an electric current through it ,a spectrum is obtained . a . Draw a spectral series of emissions lines in hydrogen b. Name the different series of hydrogen atom . c . In which region Lyman series is located .

A gas of hydrogen like ions is prepared in a particular excited state A. if emit photons having wavelength equal to the wavelength of the first line of the lyman series together with photons of five other wavelength identify the gas and find the principal quantum number of the state A
