Vedclass · Answer

(A) photon is a quantum of electromagnetic radiation. The energy $E$ of a photon is given by the relation $E = h
u$,where $h$ is Planck's constant and $
u$ is the frequency of the radiation.Since the frequency $
u = \frac{c}{\lambda}$,where $c$ is the speed of light and $\lambda$ is the wavelength,we can substitute this into the energy equation.Therefore,$E = \frac{hc}{\lambda}$.This is the correct expression for the energy of a photon.
