The wavelength of light in the visible region is about 390 nm for violet colour, about 550 nm (average wavelength) for yellowgreen colour and about 760 nm for red colour. What are the energies of photons in (eV) at the red end of the visible spectrum? `("Take h "= 6.63xx10^(-34)" J s and 1 eV" = 1.6xx10^(-19)J.)`
