उत्तर
The two characteristic properties of photons on which this equation is based are as follows:
(i) Photons have particle characteristic. It is emitted or absorbed in units called quanta of light.
(ii) Photons have wave characteristic. It travels in space with particular frequency, a characteristic of waves.
