0 17. How many photons of light having a ward 400 nm are necessary to provide 1 J of energy? I have solved it but my question is why do I have to do it in two steps and why cant I get the answer by using E=nhc/wavelength |

Answer» tion:Photons ACT as individual quanta and interact with individual ELECTRONS, atoms, molecules, and so on. The energy a PHOTON carries is, thus, crucial to the effects it has. Table 1 lists representative submicroscopic energies in eV. When we compare photon energies from the EM SPECTRUM in Figure 1 with energies in the table, we can SEE how effects vary with the type of EM radiation. |
