de Broglie equation, derivation, and its Significance Chemistry Notes
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 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.

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.
De Broglie theory (Duality) Overall Science
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.

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.

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.

De Broglie Wavelength Matter waves are the central part of the theory of quantum mechanics. All matter can exhibit wave-like behaviour. The concept that matter behaves like a wave this concept was proposed by a French physicist named Louis de Broglie in the year 1924. It is also known as the de Broglie hypothesis.

The de Broglie wavelength of the photon can be computed using the formula: λ = h p = 6.63×10−34 1.50×10−27 = 4.42 ×10−7 = 442 ×10−9 = 442 Nano meter. Therefore, the de Broglie wavelength of the photon will be 442 nm. This wavelength will be in the blue-violet part of the visible light spectrum.

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).

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
De Broglie Wavelength Formula Formula, Derivation, Applications
Through the equation λ λ, de Broglie substituted v/λ v / λ for ν ν and arrived at the final expression that relates wavelength and particle with speed. mv2 = hv λ (5) (5) m v 2 = h v λ. Hence. λ = hv mv2 = h mv (6) (6) λ = h v m v 2 = h m v. A majority of Wave-Particle Duality problems are simple plug and chug via Equation 6 6 with.

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.

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 Derivation by SK
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.
