Homework Help: De Broglie Wavelength Equation

  1. May 6, 2009 #1
    1. The problem statement, all variables and given/known data
    What was the significance of the de Broglie equation?

    2. Relevant equations
    p = h/λ
    p = mv

    3. The attempt at a solution
    It says that not only do waves act as particles, transferring energy and momentum to matter only at localised points, but moving particles (e.g. electrons) also acts as matter waves, transferring energy and momentum to other matter at points. De Broglie suggested that the first of the two above equations applied to electrons as well as photons.

    Hi everyone,
    That's what I've written so far. Is there anything I'm missing?

    Perhaps you could expand what you have written by mentioning that he was the first to propose that electrons could be diffracted.

    The hypothesis equation is in the attached image.

    Hope your French is up to this...

    "L'histoire des Sciences montre que les progrès de la Science ont constamment été entravés par l'influence tyrannique de certaines conceptions que l'on avait fini par considérer comme des dogmes. Pour cette raison, il convient de soumettre périodiquement à un examen très approfondi les principes que l'on a fini par admettre sans plus les discuter."
