Answer:
The fundamental frequency is 196 Hz.
Step-by-step explanation:
Given that,
Frequency = 588 Hz
We need to calculate the fundamental frequency
Using formula of fundamental frequency
We know that, two nodes means third harmonic
![f_(3)=3f_(1)](https://img.qammunity.org/2020/formulas/physics/college/b90hzf0pir9xo8eikxunwhk407xwjvi1pc.png)
![f_(1) =(f_(3))/(3)](https://img.qammunity.org/2020/formulas/physics/college/2mtq59vyacp8mpdk7wfl4o7iixvzxtczl4.png)
Where,
= fundamental frequency
Put the value into the formula
![f_(1)=(588)/(3)](https://img.qammunity.org/2020/formulas/physics/college/9gd8jh1vz8gvac4vzi6tjo9wx7heny6m2g.png)
![f_(1)=196\ Hz](https://img.qammunity.org/2020/formulas/physics/college/q86936zgyirjw3038kl5ix03iggi5urn6a.png)
Hence, The fundamental frequency is 196 Hz.
