Wave & Particle: What's the Difference?

In summary, the distinction between a particle and a wave in quantum mechanics is a way of interpreting QM-phenomena using our classical eyes.

I have a question about these concepts:
I know that we can see both the wave and particle properties in all paricles and wave. but...
when we call a "being" , "wave" or "particle".
where is the distinction?
thanks in advance.

The reality of the quanta is beyond us. We have a mathematical and physical undestanding of how they interact with us, but really all we have about them "at home" is some complex numbers that can be manipulated to give the probability of what they will do next. "Wave" and "particle" are the two physical behaviors that manifest when we observe them.

Isnt the "distinction" what it is, in how the quanta is Interacting with us. I also Have a question about this. I just have to think of how to ask it:)P My question being more along the lines of why when they are interacting with us, ... Hmmm going to have to think about this one:)P Probly In over my head and shutting up now heheh

The particle wave duality means that you can use either the "particle-language" or the "wave-language" when it comes to describing QM-phenomena. However you NEED to realize that this duality does NOT come from QM itself. In QM, you do NOT have this duality. It only exists because we look at the results predicted by QM with our "classical eyes"

this duality is a way of interpreting stuff like wave functions and interference properties inherent to QM. You can switch from one vision to the other but you cannot use them simultaneously. So there is NO distinction in a particle and a wave in QM!

Thanks marlon..they way I always look at a particle of energy depends on how I am applying it..I guess that would kinda answer what I was going to ask. so making the "distinction" determines if U have a wave or a particle? ...Hmm been up all night..better get some sleep before I pop a neron or 2 :zzz:

Again, you always have the same quantummechanical entity which is described by the corresponding wavefunction. Making the distiction in this case is deciding whether we look through the "particle-like glasses" or the "wave-like glasses", however the thing we are looking at is not at one moment a particle and at another moment a wave. It is a "fixed" QM-object to which we look with our classical eyes, through one of the two possible glasses.

Dear selfAdjoint, Marlon,
thanks a lot. I think I got it!
 

FAQ: Wave & Particle: What's the Difference?

What is the wave-particle duality?

The wave-particle duality is a fundamental concept in quantum mechanics that describes how particles can exhibit both wave-like and particle-like behavior.

How can light be both a wave and a particle?

This is a common question because it seems counterintuitive. However, experiments such as the double-slit experiment have shown that light behaves like a wave in some situations and like a particle in others.

What evidence supports the wave-particle duality?

The wave-particle duality has been supported by numerous experiments, including the double-slit experiment, the photoelectric effect, and the Compton effect.

How does the wave-particle duality impact our understanding of the physical world?

The wave-particle duality challenges our traditional understanding of particles as solid, tangible objects. It also has implications for the behavior of subatomic particles and the foundations of quantum mechanics.

Can we observe both the wave and particle aspects of a particle at the same time?

No, the wave and particle aspects of a particle are complementary and cannot be observed simultaneously. This is known as the Heisenberg uncertainty principle.
