- The wavelength of a spectral line for an electronic transition is inversely proportional to : (1) number of electrons undergoing transition (2) the nuclear charge of the atom (3) the velocity of an electron undergoing transition (4) the difference in the energy involved in the transition
- a photon of 3000 Angstrom is absorbed by a gas and then re-elected as two photons. One photon is red 7600 Angstrom . What wavelength of other photon? Here I am knowing solution but I am not able to understand that why we are using formula ( h*c/lambda of total = h*c/lambda of 1 +h*c / lambda of 2 ) Please solve it
