THE ENERGY OF A PHOTON IS given as delta E / atom 3.03*10-19 J per atom . then the wavelength of the photon is ? Share with your friends Share 2 Vartika Jain answered this Dear Student, We know that, E=hcλh = 6.626×10-34 Js-1c=3×108 ms-1E=3.03×10-19 J per atomSo, λ=hcE= 6.626×10-34×3×1083.03×10-19=6.560×10-7 m= 656 nm 19 View Full Answer
