SUMMARY
The discussion centers on the relationship between the work functions of metals and the threshold wavelength in the photoelectric effect. The work function, denoted as \(\phi\), is defined by the equation \(\phi = hf_{0}\), where \(f_{0}\) represents the threshold frequency. It is established that the threshold wavelength (\(\lambda\)) is inversely proportional to the work function, expressed as \(\phi = \frac{hc}{\lambda}\). This relationship indicates that as the threshold wavelength increases, the work function of the metal also increases, highlighting the intrinsic properties of the metals involved.
