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!
