[@nikitarawat4301]

Tq sir for such a very very good explanation 🙏

[@Bhababu143]

In 13:20 sir , you have written vg= dw/dk but here w=? K = ?
But I think w = (w1+w2)/2 resultant angular frequency
K= (k1+k2)/2
Resultant of propagation const
Is it correct sir ?

[@Eduphile]

No , yaha pe difference liya jata h jaise w2-w1 aur k2-k1

[@alishaanjum1108]

Sir i have one confusion ...we say that wave packets are made of many individual waves and speed of eavh individual wave is phase velocity .....if each individual wave has diff velocity thn there will be many phase velocities but acvording to relation which u derived phase velocity has got only one value w by k ? Why

[@Eduphile]

Yes, but it is for single wave

[@anshipatel9703]

Yeah ...but value of w and k is different for each wave of wave packet

Sir question shi hai

[@asifbhutta3101]

Sir de broglie ny kia group velocity ka concept diya tha??? Aur us ki velocity of wave tu :c^2/v ho gi na jo us ny thi di?

[@Eduphile]

The idea of a group velocity distinct from a wave's phase velocity was first proposed by W.R. Hamilton in 1839, and the first full treatment was by Rayleigh in his "Theory of Sound" in 1877.
