In a hydrogen like atom, when an electron jumps form the M-shell to the L -shell the wavelenght of emitted radiation is `lambda`. If the L-shell, the waveleght of emitted radiation will be:
The change in velocity when hydrogen electron jumps from K shell to L shell is
In the helium atom, the number of electrons in the L shell is
if the electron in hydrogen orbit jumps form third orbit to second orbit, the wavelength of the emitted radiation is given by
The wavelength or radiations emitted is lambda_(0) when an electron in hydrogen atom jumps from the third orbit to second. If in the H-atom itself, the electron jumps from fourth orbit to second orbit, the wavelength of emitted radiation will be
