Answer:
[tex]k=2.4*10^{-3}[1/m][/tex]
Explanation:
We can use the equation of the wave number in terms of velocity and frequency.
[tex]k=\frac{2\pi \nu}{v}[/tex]
Where:
- ν is the frequency, and we know that T = 1/ν
- v is the phase velocity
[tex]k=\frac{2\pi}{Tv}[/tex]
[tex]k=\frac{2\pi}{13*197.5}[/tex]
[tex]k=2.4*10^{-3}[1/m][/tex]
I hope it helps you!
