Vedclass · Answer

(D) The energy of a photon is directly proportional to its frequency,with the proportionality constant being Planck's constant $h$.The relationship between energy $E$,frequency $
u$,and wavelength $\lambda$ is given by $E = h
u$.Since the speed of light $c$ is related to frequency and wavelength by $c = 
u\lambda$,we can express frequency as $
u = c/\lambda$.Substituting this into the energy equation,we get $E = h(c/\lambda) = hc/\lambda$.
