SUMMARY
The discussion centers on calculating the wavelength of an ejected electron when a photon with a wavelength of 368 nm strikes a metal surface with a threshold frequency of 3.184 x 1014 Hz. The relevant equations include the relationship between frequency and wavelength, as well as the energy conservation equation: Eincident = Ethreshold + KE. To find the wavelength of the ejected electron, participants recommend using the kinetic energy formula KE = p2 / (2m) to determine momentum, followed by the de Broglie wavelength equation λ = h/p.
