The wavelength of the wave associated with any material particle was calculated by analogy with photon as follows:-In case of a photon, if it is assumed to have wave character, its energy is given by. The de Broglie relation has been modified by considering the relativistic equation for energy. The goal is not to reach a particular result. Rather, some known equations are manipulated to produce a general result. The Schrödinger equation describes the wave-function of a system, which is a quantum-mechanical property.

De broglie relation

Louis de Broglie argued that if particles had a wave nature , the relation E = hν would also apply to them, and postulated that particles would have a wavelength equal to λ = h / p .

= n)  The De Broglie Wavelength gives the wavelength of any particle traveling with linear momentum. It shows an inverse relationship between the linear momentum   The de Broglie relation, p = h/λ, says that a particle's momentum p is inversely proportional to its wavelength λ. For photons, this relation is a straightforward. The equation E=pc holds for a photon. But de Broglie relations is not about photons, is it?

Two fundamental equations regarding wave-particle duality are: $$ \lambda = \frac{h}{p}, \\ \nu = E/h .$$. We talk about de Broglie wavelength, is it meaningful to talk about de Broglie frequency ($\nu$ above) and de Broglie velocity ($\nu \lambda$)?Are these two equations independent or can one derive one from the other? Or mid-way, does one impose constraint on other? That de Broglie relation looks the same as the Planck-Einstein relation (p = h/λ) but it’s fundamentally different. Indeed, the momentum of a photon (i.e.

That de Broglie relation looks the same as the Planck-Einstein relation (p = h/λ) but it’s fundamentally different. Indeed, the momentum of a photon (i.e. the p we use in the Planck-Einstein relation) is not the momentum one associates with a proper particle, such as an electron or a proton, for example (so that’s the p we use in the de Broglie relation).

It is one of two related equations called the de Broglie equations. You can read more about de Broglie's work here. He received the 1929 Nobel Prize in Physics for this work. (I will discuss the second de Broglie equation below the following example problems.) Equation Number Two: λ = h/p De Broglie's Thesis .

De Broglie’s Equation De Broglie’s hypothesis stated that there is symmetry in nature and that if light and radiation behave as both particles and waves, matter too will have both the particle and wave nature. In this video you will learn how to calculate the wavelength of particles with the de Broglie relation. According to de Broglie, a moving material particle acts as a wave and sometimes wave is associated with moving material particle which controls the particle in every respect. `lambda = h/p` where p = Momentum of the particle. h = Planck constant 2019-06-05 NCERT Chemistry Class 11 – Unit 2 – Louis.de Broglie Relationship.
