Phase and Group Velocity in Quantum Wavepackets

[@mylegalname9852]

That gif in the lower-left from 1:15-1:25 helped so much. It was hard to visualize before that. Thank you!

I never understood this well but now it's very clear in my head. Thank you a lot!

You sir, have been a huge help. Many thanks!

[@kajalswain-Upsc]

Well explained.

[@blackcohn]

compare to EM waves, where phase velocity travels theoretically faster than the speed of light. What does group velocity travel twice the speed of phase velocity tells us about the wave packet in quantum mechanics?

Outstanding

[@reshadmussema5318]

thank u dr what about negative group velocity

[@jingcineo5815]

This is great! Thanks

Too fast i can't understand
