Chlorophyll present in green leaves of plants absorbs light at 4.620 × 1014 Hz. Calculate the wavelength of radiation in nanometer. Which part of the electromagnetic spectrum does it belong to?

Relation b/w wavelength and frequency can be expressed as :


λ = c/ϑ, where c be the velocity of light and ϑ is the frequency of the radiation.


For the given problem λ = 3 X 108 ms-1 / 4.620 X 1014 Hz


= 0.6494 times10-6m-1
