Photoelectric Effect
Summary
Experiments show that electron emission based on frequency rather than intensity. In other words, \(\nu\) yields \(e^-\) at a definite energy perportional to \(\nu\) and only after \(\nu_0\) and doesn’t depend on intensity. The number of electrons is dependent on intensity.
Takeaways
- The electron’s energy is dependent on the frequency of the incident light
- The number of electrons is dependent on the intensity of the incident light
- Einstein (1905): \(\frac{mv^2}{2}=\hbar\nu-W\), \(W=\hbar\nu_0\).
