    Electronvolt - Wikipedia, the free encyclopedia

    The fact you have such a poor understanding of your own argument and the equations you have presented leads me to think I'm wasting my time here...
    I know you said eV is a unit of energy and I am saying your are wrong in the case of this equation, eV here means "e" * "V" (V is the threshold voltage) I am trying to tell you that I did not choose on a whim or at all to just put eV there, it has relevance to the situation when discussing LEDs that emit light of distinct energies.

    e*V=h*f

    Ah, OK I see the misunderstanding I had now, when I saw eV I automatically thought electron-volt as it is a very common unit of energy and Eneergy is the parameter that has been replaced by the dimensionally equivelant e*V. (I'm not familiar with the equations use in LEDs and was projecting the way I use them for photons onto the problem, apologies for that. Though I still think you are guilty of the circular reasoning of assuming c is constant to show c is constant as I said in post #98

    Anything short of the Michelson-Morley experiment would be circular. the LED experiment is just to reaffirm it. As for the misunderstanding I am guilty of the same when I first saw that equation in my text book.

    Ha! haven't heard that one before.
