Answer 1

`k=2.4*10^(-3)[1/m]`

Step-by-step explanation:

We can use the equation of the wave number in terms of velocity and frequency.

`k=(2\pi \\u)/(v)`

Where:

• ν is the frequency, and we know that T = 1/ν
• v is the phase velocity

`k=(2\pi)/(Tv)`

`k=(2\pi)/(13*197.5)`

`k=2.4*10^(-3)[1/m]`

I hope it helps you!
