Homework Help: De Broglie Wavelength Problem

  1. Feb 20, 2007 #1
    1. The problem statement, all variables and given/known data

    What is each of the following?
    (a) the wavelength of a 6.0 eV photon
    (b) the de Broglie wavelength of a 6.0 eV electron

    2. Relevant equations


    3. The attempt at a solution

    None so far

    [tex]\lambda=\frac{h}{mv} [/tex]

    what about the velocity?
  5. Feb 21, 2007 #4
    nevermind use this formula

    [tex] f = \frac{E}{h} [/tex]

    and [tex] c = \lambda f [/tex]

    by th way this is probably in your textbook or in your notes...

    you can also look this up on wikipedia, for example

    I've already solved part a. The De Broglie wavelength is given by the equation [tex] lambda=h/p [/tex].
