20. The data given below gives the photon energy (in eV) for a number of waves whose wavelength values (in nm) are also given.
Photon Energy (in eV)
(Without doing any calculation/taking any reading), explain how one can use this data to draw an appropriate graph to infer
(i) photon energy corresponding to a wavelength of 100 nm.
(ii) the wavelength value (in nm) corresponding to a photon energy of 1 eV.
(iii) velocity of light assuming that the value of Plank’s constant is known.
