Vedclass · Answer

(B) When white light falls on a coordination complex,it absorbs light of a specific wavelength corresponding to the energy of the $d-d$ transition.The colour observed by the human eye is the complementary colour of the light absorbed by the complex.If the crystal field splitting energy $(\Delta_o)$ is high,light of shorter wavelength (higher energy) is absorbed,and the complex appears to have a colour corresponding to a longer wavelength.

What is the relationship between the observed colour of a coordination complex and the wavelength of light absorbed by it?
