de Broglie wavelengths. ( = h/p = h/mv = h / ((2m.K) If the all the particles all have the same energy, then ( will depend inversely on the square root of the mass. The electron will have the smallest mass and hence the greatest wavelength, the ( particle will have the shortest wavelength and the neutron and proton will be in between.

Discussion: de Broglie equation. In 1923 Louis de Broglie proposed that a particle of momentum p would have a wavelength λ given by the equation: wavelength of particle λ = hp. where h is the Planck constant, or λ = hmv for a particle of momentum mv. The formula allows us to calculate the wavelength associated with a moving particle.

A physicist de Broglie came up with a great equation that allows you to calculate the wavelength of something. The formula is: = h . m wavelength, h = Planck’s constant 6.626 x 10 -34 J*s, m = mass in kg , = frequency. n automobile moving at 25 m/s and having a mass of 910 kg would have a wavelength of 2.9 x 10 -38 m a wavelength that can’t be detected with even the most sensitive instrument.
