Vedclass · Answer

(A) The smallest discrete packet or bundle of energy is called a quantum of energy. In the case of electromagnetic radiation,this quantum is known as a $Photon$.The energy of a photon is given by the equation $E = h
u$,where $h$ is $Planck's$ constant and $
u$ is the frequency of the radiation.Alternatively,since $
u = c/\lambda$,the energy can also be expressed as $E = hc/\lambda$,where $c$ is the speed of light and $\lambda$ is the wavelength.
