Wavelength (in nm) 200 400 600 800 1000 1200

Photon Energy (in eV) 6.216 3.108 2.072 1.554 1.243 1.036

(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.
