An atom emits a spectral line of wavelength `lambda` when an electron makes a transition between levels of energy `E_(1) and E_(2)`. Which expression correctly relates `lambda E_(1) and E_(2)` ?

The wavelength lambda_(e ) of an electron and lambda_(p) of a photon of same energy E are related by

The wavelength lambda_(e ) of an electron and lambda_(p) of a photon of same energy E are related by

The wavelength lambda_(e) of an electron and lambda_(P) of a photon of same energy E are related by:

Transition between three energy energy levels in a particular atom give rise to three Spectral line of wevelength , in increasing magnitudes. lambda_(1), lambda_(2) and lambda_(3) . Which one of the following equations correctly ralates lambda_(1), lambda_(2) and lambda_(3) ?

Transition between three energy energy levels in a particular atom give rise to three Spectral line of wevelength , in increasing magnitudes. lambda_(1), lambda_(2) and lambda_(3) . Which one of the following equations correctly ralates lambda_(1), lambda_(2) and lambda_(3) ? lambda_(1)=lambda_(2)-lambda_(3) lambda_(1)=lambda_(3)-lambda_(2) (1)/(lambda_(1))=(1)/(lambda_(2))+(1)/(lambda_(3)) (1)/(lambda_(2))=(1)/(lambda_(3))+(1)/(lambda_(1))
