3.1 de Broglie Waves. Recall that a photon has energy E=hf, momentum p=hf/c=h /λ, and a wavelength λ=h/p. De Broglie postulated that these equations also

A baseball thrown at a pitcher has a de Broglie wavelength that is smaller than the diameter of a proton by about 20 orders of magnitude. The wave aspects of a macroscopic object are so tiny as to be unobservable in any useful sense, although interesting to muse about.

This chemistry video tutorial explains how to calculate the de broglie wavelength of large objects and small particles such as electrons. It contains plenty For an electron with KE = 1 eV and rest mass energy 0.511 MeV, the associated DeBroglie wavelength is 1.23 nm, about a thousand times smaller than a 1 eV photon. (This is why the limiting resolution of an electron microscope is much higher than that of an optical microscope.) The wavelength of a particle, given by \lambda = {h\over p}, where h is Planck's constant and p is the momentum. In the nonrelativistic limit, this can be written \lambda={h\over mv}, where m is the particle mass and v is the velocity.

This De Broglie equation is based on the fact that every object has a wavelength associated to it (or simply every particle has some wave character). This equation simply relates the wave character and the particle character of an object. The De Broglie Equations. The de Broglie equations relate the wavelength (λ) to the momentum (p), and the frequency (f) to the kinetic energy (E) (excluding its rest energy and any potential energy) of a particle: [latex]\lambda ={ h }/p[/latex] and [latex]f={ E }/{ h }[/latex] where h is Planck’s Constant. The two equations can be The obtained wavelength is nothing but the Compton wavelength in the Compton effect with correction for the Lorentz factor..

The electron has the longer de Broglie wavelength. Since λ = h/p = h/(mvγ) and the proton has a much higher mass, it has larger momentum and hence a shorter
