Vedclass · Answer

(B) The energy of a photon is given by the equation $E = \frac{hc}{\lambda}$,where $h$ is Planck's constant,$c$ is the speed of light,and $\lambda$ is the wavelength.From this relation,it is clear that $\lambda = \frac{hc}{E}$.Therefore,the wavelength of the emitted spectral line is inversely proportional to the energy of the photon,i.e.,$\lambda \propto \frac{1}{E}$.

The wavelength of a spectral line emitted is inversely proportional to:
