de Broglie equation Science, quantum theory ShowMe
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.
De Broglie Wavelength Formula Equation, Concept, Solved Examples
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 Wavelength Formula Formula, Derivation, Applications
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.

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.

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.

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'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.
What is the significance of de Broglie's equation? Quora
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 wave equation Derivation by SK
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 equation, derivation, and its Significance Chemistry Notes
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.

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.
