# Is there any difference between de-Broglie wavelength and the wavelength of normal waves?

Is de-Broglie wavelength different from wavelength of waves such as electromagnetic waves?

If yes, they differ in what respect?

And can we use the formula of wavelength of light ($c=v\lambda$) to calculate the de-Broglie wavelength?

• de-broglie wavelength is the wavelength associated with a particle with mass. h/p=de-broglie wavelength, where p is momentum, h is planck's constant. Sep 9 '15 at 18:56
