Question

I would appreciate if you can help me solve this problem. I’m having trouble with it

Answer 1

The frequency of a wave is given by:

`f=(v)/(\lambda)`

Where v is the speed of the wave and lambda is the wavelenght. In this case the speed is 345 and the wavelenght is 0.85 meters; plugging the values given we have:

`\begin{gathered} f=(345)/(0.8) \\ f=431.25 \end{gathered}`

Therefore the frequency of the wave is 431.25 Hz
