Optics and Optical Design - Dispersion: Phase Velocity Versus Group Velocity, PHYS 372

The distinct meanings of group velocity and phase velocity are demonstrated, both conceptually and with a little math. As part of a series of lectures on quantum mechanics, this video explores an important characteristic of the quantum mechanical wave function. The dispersion of a quantum mechanical free particle is treated as an illustration. I don't ask for support for this content so please click "Like" whenever you feel it's appropriate. It's difficult to measure the success of this channel. My only metric of success is that the videos help people to do what they do better. How do you measure that? The only signal for success comes from the likes. #Dispersion #GroupVelocity #FreeParticle #PhaseVelocity
