# SOLVED:Can a particle be diffracted? Can it exhibit interference?

### Video Transcript

this trouble asks us if particles can be deflected if they can go through hindrance. Basically, if they can exhibit demeanor that is characteristic of ways. In order to answer the interview, we need to remember off the quantum mechanics wave particle dichotomy. And I ‘m gon na give you a brief explanation by remembering about the Debra Lee wavering. So remember that according to the beefy, each atom has the momentum p that is equal to plus constant age, divided by the wavelength from the of the particles. So this means that evening massive particles have a certain wavelengths. sol and I think, for example, uh, and in in and even you and me, we all have wavelengths associated with our momentum, our momentum. But of course, since our momentum is M. Times v. London, that is the wavelength is long time divided by M. V. indeed if our mass is very large, or our focal ratio is very large or even a regular accelerate and masses. so, for exemplar, a person that has a mass off 70 kg on a focal ratio of 1 m per second, this would result in a identical modest value off the wave line. Because remember that age is 6.63 times sin the minus 34 jewel second. sol, in rate to make up for this very little number, the bulk and or the rush or both must be very little. so normally we do n’t see crinkled demeanor because, uh, the wavelength is identical little. And in regulate for us to see crinkled behavior like diffraction and hindrance, um, a wave must have a vacillant that is about the lapp. Uh, that is about the value off the whole the wave is passing through. So, for example, if we have at the diffraction diffraction phenomenon where a roll passes through a hole that has a diameter D then we expect that in order to see the diffraction phenomenon the wavelength off the wave Lunda must be off the club of magnitude of D. So it must be about deep. Okay, then in principle, we could exhibit crinkled behavior so we could refract we could interfere, but we normally do n’t do those things we do n’t. We do n’t effect we and we do n’t interfere because we have a identical belittled wavelengths and for case, in order for you to interfere or to defect when you pass through a door the door would have to have. Ah, with that is very, identical small. much smaller than the radios off a typical Adam. But electrons, for exemplar, do the fact they do interfere with each early. Eso in in, uh, in the end, the suffice. Your question is yes, they can do both. Both because particles show wave like behavior. Mhm. And this is the answer to a interview.
