  • a)
    1/2 ck
  • b)
    ck
  • c)
    2ck
  • d)
    4ck

Verified Answer
The relationship between the angular frequency co and the wave number ...
The wave equation y= a sin(ωt - kx)
phase velocity = ω/k
Group velocity = dω/dk
We have ω= ck2

The relationship between the angular frequency co and the wave number ...
Group velocity =dw/dk
so solve given relation
we have
w=k².c
now dw/dk =2kc
