I Correlation between size and mass of particles

[Ranku]

Is there a correlation between the size of a matter particle (defined as its matter wavelength) and the mass of the particle? With the photon, its wavelength and its energy/mass are inversely correlated. Is it also true of matter particles?

And what do you mean by "matter wavelength" and why should it be considered as particles size? If it's de Broglie wavelength then just check the formula for it.

de Broglie wavelength depends on the momentum of the particle, not its mass.

How else to consider particle size?

 

[weirdoguy]

Well, elementary particles (like electron) are considered to be point-like, that is, they don't have size.

Since de Broglie wavelength = h/momentum = mass x velocity, that would give us an indirect sense of the ‘size‘ of the particle, in relation to its mass.

How?

de Broglie wavelength = momentum

Nope, that's not the formula, but you're close.

Thgis started out as a question with a simple answer - "there isn't one". Why are you (the OP) trying to morph this qu4estion into one with a different answer?
