- In the explanation of photo electric effect, we asssume one photon of frequency $ν$ collides with an electron and transfers its energy. This leads to the equation for the maximum energy $E_\text{max}$ of the emitted electron as,
- $\text{E}_\text{max}=\text{hv}-\phi_0$
where $\phi_0$ is the work function of the metal. If an electron absorbs $2$ photons $($each of frequency $ν)$ what will be the maximum energy for the emitted electron? - Why is this fact $($two photon absorption$)$ not taken into consideration in our discussion of the stopping potential?
