Which wavelength will be emitting by a sample of atomic hydrogen gas (in ground state) if electron of energy `12.2eV` collide with the atoms of the gas?

The radius of hydrogen atom, in the ground state is of the order of

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

Energy of an atom at its ground state is _________ .

An electron with kinetic energy 5eV is incident on a hydrogen atom in its ground state.The collision

A beem of ultraviolet radius hacking wavelength between 100nm and 200nm is inclined on a sample of atomic hydrogen gos Assuming that the atoms are in ground state which wavelength will have low intensity in the transnilled been? If the energy of a photon is equal to the ground state it haslarge probobility of being observed by on atom in the ground state
