A) k
B) w
C) k/w
D) kw
Correct Answer: C
Solution :
The angular wave number \[k=\frac{2\pi }{\lambda };\] where l is the wave length. The angular frequency is \[w=2\pi \nu .\] The ratio \[\frac{k}{\omega }=\frac{2\pi /\lambda }{2\pi \nu }=\frac{1}{\nu \pi }=\frac{1}{c}\]= constantYou need to login to perform this action.
