- 30Frequency threshold is when...?Ek max = O
so.. hf = work function - 31If light is a wave, what 3 simple predictions could be made about the photoelectric effect?1.) There would be a delay between the moment the electron receives the energy and the time it is ejected.
2.) Ek would be proportional to Intensity
3.) Should occur for any frequency - 32Derive equation for momentum of a photonP = mv = mc
E= mc^2 (m = E/c^2)
P = E/C (E = hf )
P = hf/C C=wavelength x f
P = h/wavelength - 33De Broglie Wave lengthwavelength = h/p = h/mv
