SUMMARY
The discussion centers on the photoelectric equation, specifically the relationship between stopping voltage (V0), frequency (f), Planck's constant (h), and the work function (w0). The equation is rearranged to V0 = (h/e) * f - (w0/e), where V0 represents stopping voltage, h is Planck's constant, e is the electron charge, and w0 is the threshold frequency. The user seeks clarification on the SI units for h/e and w0/e, noting that Planck's constant has units of Joules-seconds (Js) and the work function is expressed in electronvolts (eV), which is equivalent to Joules (J).
