I cannot understand what is the colour of water.I was reading an Optics book by Hecht,& suppose that we see coluured bodies due to Dissipative absorption.That is taking up of incident photon,converting a part into thermal energy,and releasing the rest energy as another photon.But, ordinarily we say water colourless.What wavelength is actually emittted?
