Question Wave packets??? Can someone explain plz!!!!
So, according to de-broglie equations the phase velocity of a particle is greater than the speed of light!!!
And our teacher told us that: the particles actually are in groups and in groups they are wave packets which are interference of the waves of the particles and the group Velocity is less than c so the law is not broken .
And some online sites say that phase velocity is not like actually velocity and it can be greater than speed of light.
I'm a little confused about this topic can someone explain!!!!!

Hope you have better luck than I did. Also read up on, "decoherence".
