Question Video Identifying the de Broglie Relationship Nagwa
Derivation de Broglie derived the above relationship as follows: 1) E = hν for a photon and λν = c for an electromagnetic wave. 2) E = mc 2, means λ = h/mc, which is equivalent to λ = h/p. Note: m is the relativistic mass and not the rest mass since the rest mass of a photon is zero.
De Broglie's Formula YouTube
Compton's formula established that an electromagnetic wave can behave like a particle of light when interacting with matter. In 1924, Louis de Broglie proposed a new speculative hypothesis that electrons and other particles of matter can behave like waves. Today, this idea is known as de Broglie's hypothesis of matter waves.In 1926, De Broglie's hypothesis, together with Bohr's early.
What is the significance of de Broglie's equation? Quora
Now comes the second equation. 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

The de Broglie equation is an equation used to describe the wave properties of matter, specifically, the wave nature of the electron : λ = h/mv, where λ is wavelength, h is Planck's constant, m is the mass of a particle, moving at a velocity v. de Broglie suggested that particles can exhibit properties of waves.
De Broglie theory (Duality) Overall Science
De Broglie's hypothesis is an independent postulate about the structure of nature. In this respect, its status is the same as that of Newton's laws or the laws of thermodynamics. Nonetheless, we can construct a line of thought that is probably similar to de Broglie's, recognizing that these are heuristic arguments and not logical.
De Broglie Wavelength Formula Equation, Concept, Solved Examples
The de Broglie equation is one of the equations that is commonly used to define the wave properties of matter. It basically describes the wave nature of the electron. Electromagnetic radiation exhibits the dual nature of a particle (having a momentum) and wave (expressed in frequency and wavelength).

Solution: Reasoning: The de Broglie wavelength of an object is defined as λ = h/p. Details of the calculation: λ = h/p, E = p 2 / (2m), p = √ (2mE), λ = h/√ (2mE). The energy of the electron is 25000 eV * 1.6*10 -19 J/eV = 4*10 -15 J. λ = (6.626*10 -34 Js)/√ (2*9.1*10 -31 kg*4*10 -15 J) = 7.8*10 -12 m.
PM [D02] de Broglie deriving the Equation
In 1924, French scientist Louis de Broglie derived an equation, known as the De Broglie Wavelength Formula, that described the wave nature of any particle. Thus, establishing the wave-particle duality for the matter. Microscopic particle-like electrons also proved to possess this dual nature property.

De Broglie was able to mathematically determine what the wavelength of an electron should be by connecting Albert Einstein's mass-energy equivalency equation (E = mc 2) with Planck's equation (E = hf), the wave speed equation (v = λf ) and momentum in a series of substitutions.
Question Video Relating Momentum to the de Broglie Wavelength Nagwa
To determine the de Broglie wavelength of a particle given its mass and velocity, you need to: Multiply the velocity by mass. Their product is the particle's momentum. Divide Planck's constant by the momentum found in Step 1. The result you've got is exactly the de Broglie wavelength of your particle. Congrats!

De Broglie hypothesis Propagation of de Broglie waves in one dimension - real part of the complex amplitude is blue, imaginary part is green. The probability (shown as the color opacity) of finding the particle at a given point x is spread out like a waveform; there is no definite position of the particle.
