Question regarding particles and wavelength

AI Thread Summary
The discussion clarifies the concept of wavelength in the context of particle/wave duality. It specifies that when referring to the wavelength of a particle, it pertains to the wavelength of the wavefunction associated with a specific momentum eigenstate. This interpretation aligns with de Broglie's theory. Understanding this distinction is crucial for grasping quantum mechanics. The conversation emphasizes the importance of wavefunctions in describing particles at the quantum level.

Homework Statement


I know about particle/wave duality; however, when I read a passage and it says the wavelength of the particle I'm not sure what it's referring to. Is it the actual wavelength of the particle or the wavelength of the wavefunction for a particular eigenvalue?

It's the wavelength of a wavefunction corresponding to a particular momentum eigenstate of the particle. So, yes, the latter. See de Broglie.

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
