Careful spectral analysis shows that the familiar yellow light of sodium lamps (such as street lamps) is made up of photons of two wavelengths, 589.0 nm and 589.6 nm. what is the difference in energy (in joules/mol) between one mole of photons with these wavelengths?
Answers: 3
![\Delta E=hc\times [\frac{1}{\lambda_1}-\frac{1}{\lambda_2}]](/tpl/images/0328/2709/df32b.png)
= difference in energy of photon = ?
= wavelength of photon 1 = 589.0 nm = 
= wavelength of photon 2 = 589.6 nm = 
![\Delta E=(6.626\times 10^{-34}Js)\times (3\times 10^8m/s)\times [\frac{1}{589\times 10^{-9}m}-\frac{1}{589.6\times 10^{-9}m}]](/tpl/images/0328/2709/ce225.png)
