While an electron has properties of a particle, the de Broglie equation may be used to describe its wave properties. de Broglie suggested combining a couple of formulas, one of them a particle type, the other a wave type. p=mv p= h mv= h = h mv λ = wavelength (m) h = Planck's Constant (always 6.63e-34) m = mass (kg) v = velocity (m/s) This formula allows us to calculate the de Broglie Wavelength of a moving particle. For an object to have a wavelength, it For particles with mass (electrons, protons, etc., but not photons), there is another form of the de Broglie wavelength formula. At non-relativistic speeds, the momentum of a particle is equal to its rest mass, m, multiplied by its velocity, v. The deBroglie Equation: Relating a Particle's Energy to its Wavelength.

de Broglie suggested that particles can exhibit properties of waves. wavelength (λ) Apply the de Broglie wave equation λ = h mv λ = h m v to solve for the wavelength of the moving electron. Step 2: Calculate λ = h mv = 6.626×10−34J⋅s (9.11×10−31 kg)×(3.00×108 m/s) = 2.42×10−12 m λ = h m v = 6.626 × 10 − 34 J ⋅ s (9.11 × 10 − 31 kg) × (3.00 × 10 8 m/s) = 2.42 × 10 − 12 m The formula relates the wavelength to the momentum of a wave/particle. For particles with mass (electrons, protons, etc., but not photons), there is another form of the de Broglie wavelength formula.

What you have there isn't actually de Broglie's equation for wavelength. The equation you should be using is λ = h p And although photons have zero mass, they do have nonzero momentum p = E / c.

De broglie wavelength equation

Particularly, the wavelength (λ) of any moving object is given by: (5.8.1) λ = h m v In this equation, h is Planck's constant, m is the mass of the particle in kg, and v is the velocity of the particle in m/s.

) in a box of length L. I'll refer to these as the Einstein and de Broglie relations, respectively, after the two physicists probably already familiar with both of these equations, but let's review where they But de Broglie proposed that every pa The theory of wave--particle duality developed by Louis-Victor de Broglie Thus, the de Broglie equation suggests that the wavelength ( ) of any object in  Aug 3, 2011 λ=hp. In 1923, Louis de Broglie proposed that this equation not only holds for photons, but also  v = velocity (m/s).

Probability: The Heisenberg Can we prove the de Broglie concept using Heisenberg .
