Since electrons have a rest mass, unlike photons, they have a de Broglie wavelength which is really short, around 0.01 nanometers for easily achievable speeds. This means that a microscope using electron "matter waves" instead of photon light waves can see much smaller things. 3 comments.

λ dB = h / mv. This tells us that each particle has a wavelength. The implications of this statement are really groundbreaking. It implies that not only small particles like electrons but also atoms, molecules, and even we have a wavelength.

Is de-Broglie wavelength different from wavelength of waves such as electromagnetic waves? I would atually say no, there is no difference, since the wavelength is purely mathematical characteristic of a wave, the distance over which the wave's shape repeats.

In this brief note I show that the quantum length, equal to the cube root of the quantum volume. De Broglie wavelength is the wavelength associated with a matter wave. Matter, though it can behave like particles, also behaves like a wave.

De broglie wavelength

In 1927, experiments were done that showed electrons behaved as a wave (by showing the property of diffraction and interference patterns). In 1937, the Nobel Prize in Physics was awarded to Clint Davisson and George Thomson (son of J.J. Thomson) for this work. The respective de Broglie wavelength λ dB depends on h, the mass m of the particle and their speed v. λ dB = h / mv.

De broglie wavelength

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.

De Broglie Wavelength Calculator Wavelength is the distance between one peak of a wave to its corresponding another peak which has same phase of oscillation. It is represented by λ. The wavelength of a wave traveling at constant speed is given by λ = v/ f.

In 1924 Louis de Broglie theorized that not only light posesses both wave and particle properties, but rather particles with mass - such as electrons - do as well. The wavelength of these 'material waves' - also known as the de Broglie wavelength - can be calculated from Planks constant h divided by the momentum p of the particle.

The wave aspects of a macroscopic object are so tiny as to be unobservable in any useful sense, although interesting to muse about. 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 equivalently written as 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.) 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.
