  Chlorophyll present in green leaves of plants absorbs light at \[4.62\times {{10}^{14}}Hz.\]Calculate the wavelength of radiation) nanometer. Which part of the electromagnetic spectrum does it belong to?

Answer:

  Wavelength \[\lambda =\frac{c}{v}=\frac{3\times {{10}^{8}}}{4.62\times {{10}^{14}}}m\] \[=6.493\times {{10}^{-7}}m=6493\times {{10}^{-10}}m\] = 6493\[\overset{{}^\circ }{\mathop{\text{A}}}\,\] (Belongs to visible region)
