    What Determines the Frequency of a de Broglie Wave?

    Ok i did some math, but am no close to solution. I am able to reconcile Special Relativity energies, and I am also able to relate it to the dB wave's energy. But not sure if i still understand it. Here is what I did. Take an electron traveling at 2.5 x 108 m/s (relativistic effects will be...

    What Determines the Frequency of a de Broglie Wave?

    Do you mean to say if i plugged in the relativistic formula for Mass, hf will be equal to the rest energy (m0c2) plus kinetic energy of particle mv2/2 (where m0 is rest mass and m is the relativistic mass)? I also understand dB waves have phase and group velocities (and phase velocity is...

    What Determines the Frequency of a de Broglie Wave?

    Using this relation, energy of wave = hf = mv2. What does mv2 mean? We know mv2/2 is K.E. of the particle. Why is the energy of dB wave twice the K.E.?

    What Determines the Frequency of a de Broglie Wave?

    So if the wavelength of an electron is 1.2 x 10e(-10), what is its frequency? Knowing λ, I can calculate the electron's velocity as v = h/mλ. I get v = 6.07 x 10e(6). And now f = v/λ, which comes to 5.05 x 10e(16). Is this right?

    What Determines the Frequency of a de Broglie Wave?

    I am confused about de Broglie waves. we know λ = h/mv What is the frequency of the dB wave? Generally, speed of any wave v = fλ. Is the frequency of dB wave f = v / λ, where v is the speed of the particle (ignoring Special relativity effects)?
