Why do we take vrms speed in de broglie wavelength not average speed for a gas
While solving many questions, I came across many solutions where we took v as vrms speed for de broglie wavelength of a gas but why can't we take v as average speed as it would give us average ...

Rigorous derivation of DeBroglie wavelength
I've scoured the internet as much as I can, and I've yet to find a rigorous derivation of the DeBroglie wavelength. They all go something like this:
$$E=\gamma mc^2, \ \gamma \approx 1 \ \therefore\ E=...

What exactly is matter wave?
Wavelength of matter wave is given by de-broglie as h/p. I want to know wavelength of what wave is being discussed, or specifically what is matter wave? Is it the 'group wave' that has same velocity ...

Is there an intuitive explanation as to why the de Broglie wavelength is inversely proportional to the particle's momentum? [duplicate]
Is there an intuitive explanation as to why the de Broglie wavelength of a particle (say a photon) is inversely proportional to its momentum? It can be shown, mathematically, that:
$$E = h\dfrac{c}{\...

Is wavelenth of a particle relative according to Wave Particle Duality?
De Broglie's equation regarding the wave particle duality of matter $\lambda =\frac{h}{mv}$ depends on velocity. Now, velocity is relative and depends on the frame of reference of the observer. But ...

Difference between de Broglie wavelength and electromagnetic wavelength?
So we have to find the ratio of wavelength of electrons in 1st and 4th orbit of an atom. Why do we have to use de Broglie wavelength and not $E = \frac{h c}{\lambda}$ ?

What defines an 'object' with regards to particle-wave duality?
If any object, such as a ball, can exhibit wave behavior, I am confused about how such an object is defined. Does a ball itself have a wavelength? Does every single atom that composes it have a ...

What is exactly mean by wavelength in De Broglie equation?
I'm wondering what exactly is meant by the wavelength in De Broglie formula $p=\frac{h}{\lambda}$, where $p$ is the momentum of a particle and $\lambda$ is the wavelength. I know that a wave function ...

Does Wave-Particle Duality Mean "Particles" are Just Waves With Short Wavelengths?
I have the following question about wave-particle duality:
Are particles really just waves with short wavelengths?
If this is correct, would it then be accurate to say:
"everything in the ...

Is de Broglie wavelength and wavelength of the wave function of the particle the same thing or different?
Are de Broglie wavelength and wavelength of a wave function the same thing? I know that de Broglie proposed that all matter exhibit wave particle duality. He proposed that the Waves of these matter ...

De Broglie wavelength and wave function
Is the De Broglie wavelength of a quantum entity same as the wavelength of its wave function?
If yes, why? If no, why? If it is true only under certain circumstances, what are the conditions?

Does velocity make sense if it is small relative to the de Broglie wavelength?
What does it mean if a particle has, say, de Broglie wavelength of $100m$ and a velocity of $1 m/s$? Is it even possible to have such a setup? I don't see why not, since we can always slow the ...

What is the significance of the de Broglie wavelength? [duplicate]
I have just learnt quantum physics in school and learnt the concept of wave-particle duality.
But I still have trouble understanding what the de Broglie wavelength is. What does it mean for a particle ...

De Broglie wavelength of composite systems
Can the De Broglie wavelength of a composite system (like a molecule) be derived as opposed to being calculated from the composite mass?
EDIT:
@Dr jh, interesting relation you have derived. However, ...
