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