### Can a macroscopic body have wavelength as that of electron? [duplicate]

Einstein has suggested that light can behave as a wave as well as like a particle i.e, it has dual character. In 1924, de-Broglie suggested that just as light exhibits wave and particle properties, ...

### Will a football (soccer) diffract? [duplicate]

Apparently all objects have wavelike properties, so, if we kick a football (soccer ball, if you must) through a pair of posts, does the ball in any sense diffract? If this is ridiculous then let me ...

### Can we find a wave function for a planet orbiting the sun? [duplicate]

I have only recently started to learn quantum mechanics and I have only gone so far as to solve the hydrogen atom using Schrödinger's equation and the corresponding Hamiltonian, but all this has me ...

### Do quantum physics apply universally at all scales? [duplicate]

Do quantum physics apply universally at all scales? Where do quantum physics apply? Does the nucleus of an atom abide by the laws of quantum physics? Like do we know the definitive/velocity ...

### Why does the wave-particle duality become unnoticeable with more mass? [duplicate]

According to the formula $λ=h/mv$ for the De Broglie wavelength, as the mass increases, it becomes a greater coefficient to multiply the velocity by, and the larger number in the denominator makes the ...

### Can human have a long wavelength if he moves slowly enough? [duplicate]

According to the De Broglie hypothesis, wavelength equals to h/mv(m-mass, v-velocity, h-Planck constant), so by moving at a slow speed, that is reducing the v(velocity factor) can human beings with ...

### Is there a hard upper bound to the deBroglie wavelength of a particle with vanishing momentum? [duplicate]

This is probably a stupid and simple question, but does the heisenberg uncertainty principle set this upper bound? That knowledge of the momentum is limited, so it can't reach a very low value and ...

### de Broglie's Hypothesis [duplicate]

I've recently understood de Broglie's hypothesis, and I understand that a necessity for electrons to show diffraction is that the size of the aperture they pass through must be of the order of their ...

### Why isn't everthing in a superposition state? [duplicate]

I know that a superposition is a state in which there are 50% and 50% (other % also) chances of two things to happen so why am I not in a superposition state? Example, I am at rest and i now choose to ...

### If the particles show uncertainity ,then why the body made of particles cant show that? [duplicate]

What i want to know is that if the properties of the quantumn nature reduses if the particles combine? Or were we missing any fundamental relation to particle or boby made up of particles?

### Can massive objects behave as a wave? [duplicate]

I have used the word object but I'd be referring to particles as in the context, the objects would be comparatively very small. Consider the de Broglie's equation:  \lambda = \frac{h}{mv} \...

### Wave particle duality [duplicate]

Can someone please explain wave particle duality for large bodies? Why don't large bodies exhibit wave like nature for example if I am walking with some momentum, the wavelength associated with me is \$...

### Application of uncertainty principle [duplicate]

why doesn't Heisenberg's uncertainty principle also work for macroscopic bodies which are in-turn made up of quantum-particles? ps: if proof is provided it will be a lot more useful.
