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.

de Broglie Wave Equation. Planck's investigation of the emission spectra of hot objects and the subsequent studies into the photoelectric effect had proven that light was capable of behaving both as a wave and as a particle. It seemed reasonable to wonder if electrons could also have a dual wave-particle nature. In 1924, French scientist Louis.
De Broglie Wavelength Formula Equation, Concept, Solved Examples
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.

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.

The De Broglie wavelength of a particle is derived by using the formulas for its energy. Consider a photon of mass m with energy as E, wavelength as λ and velocity equal to speed of light, c. The energy (E) of a photon is given as, E = hc/λ ⇢ (1) Also we know that, E = mc 2 ⇢ (2) Equating (1) and (2) we get, hc/λ = mc 2. h/λ = mc.
What is the significance of de Broglie's equation? Quora
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 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.

Is it a particle or a wave? This is the question that physicists of the 1920s were asking about light. In 1924, Louis de Broglie took this question to another level as he explored how electrons - which are matter, and were thought to be simply particles - can behave like waves.

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!

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).
