Always these old ass vids that help us in the end time

If in case, I watch this video earlier, than my rank would be improved Jam physics..
Thank you for masterpiece.

Ek no.... Sir bhot simple tarike sai smjha diya apne.. 🙏🙏🙏

[kumarisushma]

Thanks sir for making me understand the relation between phase velocity and group velocity

[_riya_]

Sir it is very useful and easier to understand before 1 day of exam😅

[Einnjene]

U have made this relation as much easier as I never thought thanks. A lot sir

[Wise_me]

sir this helps me a lot thank you very much sir i will try my best to recommend your channel to as many of my frnds...

[DevendraSingh-xdbj]

your both the videos are good.
thank you sir
good job

In dispersive and nondispersive medium group velocity and phase velocity will be different.

[rakeshawati]

Nice sir in very short step thanks a lot

[heroflicks]

Mere saare problems ke solutions aap hi ke channel par hai sir 🙏

[pradeepbose]

Is the medium dispersive or non dispersive & will phase velocity & group velocity change concerned with the medium

[sivakumar.v]

Sir when we differentiate with respect to k then vp is constant only sir why we differentiate in uv method
