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


Wavelength, λ=cv
Given, frequencyv=4.620×1014Hzor4.620×1014s-1
λ=cv=3×108ms-14.620×1014s-1
=0.6494×10-6m
=649.4nm[1nm=10-6m]
Thus, it belongs to visible region.
