So, for example, red light and ultraviolet light of the same intensity should knock out the same number of electrons, and the maximum kinetic energy of both sets of electrons should also be the same. Decrease the intensity, and you should get fewer electrons, flying out more slowly; if the light is too faint, you shouldn't get any electrons at all, no matter what frequency you're using. > > This is typical of the lies and misinformation used by critics > of the wave model to discredit a wave model. > First of all it is a fundamental observation of resonant > systems, as with atoms in a wave model, that only narrow > ranges of input frequencies can generate a sympathetic > resonance in the same system.

Exactly as not observed in the photoelectric affect. There is a threshold frequency, below which the effect is absent, and above which the effect is noted. If this were a resonance effect, then frequencies significantly above the threshold frequency would also not produce the effect. This is hugely at variance with the experimental result. Sylvia.

Its a complex picture I admit. But notice that the lower threshold *varies* for each element. Thats consistent with different resonant frequencies for each element. Different resonant systems have different responses. But if your argument were true, and yes Ive looked at the kinetic energy vs frequency graphs you refer to, one would not get different spectral responsivity for different elements in solar panels. Obviously certain frequencies above threshold levels are NOT producing the effect the graph insinuates of a smooth ever increasing response to frequency. Your model gets around this with various excuses ( like bandgaps) based on various particle based theoretical explanations. A resonant system can also have more than one resonant frequency. This is obvious from spectra of atoms. At certain frequencies the atomic spectra varies in intensity. Thats how we measure redshift for instance.

Solar panels are semiconductors, with hugely more complexity than just ejecting electrons into a vacuum. Sylvia.

Exactly. You have erroneously constructed a model that is based on particles to explain what is actually a wave only based resonance. >> > But if your argument were true, and yes Ive looked at the > kinetic energy vs frequency graphs you refer to, one > would not get different spectral responsivity for different > elements in solar panels.

Having looked in more detail at your erroneous claims I realize now where you have fiddled the data. Your models claim that the only difference between photoelectric and photovoltaic effects are that the imaginary " electrons" are ejected into a vacuum or a conductor respectively. In fact this is a lie. Photolectric effect has a potential difference applied. Whereas Photovoltaic does not. In other words you and others claim that the electrical discharge is caused only by a photon impacting on the metal. That is total nonsense, propagated for a hundred years. In fact thats what happens only in the photovoltaic effect. And it is not a smooth continuum vs frequency contrary to your claims In the photoelectric effect would you get your imaginary electron ejected without the pd? No. Shine a light on a solar panel without an applied potential and you do still get a current induced, but only at particular resonant frequencies. Obviously you cannot claim that the photoelectric effect can be explained solely by a photon hitting the metal. Why? Because you conveniently forgot to mention the applied pd.
