Faster than speed of light

Postby JimmyThyJoker » Thu Aug 24, 2017 5:54 pm

Phase velocity can be faster the speed of light while the group velocity can't.
Which waves of the group are actually travelling at the phase velocity? If we can find them, aren't we going to be able to break the speed barrier?
