Step 1:
I'll solve this problem by providing a clear, step-by-step explanation of the fundamental frequency equation.

Step 2:
: Define Fundamental Frequency

The fundamental frequency is the lowest frequency of a vibrating system, such as a string or air column. It represents the first harmonic or primary mode of vibration.

Step 3:
: Fundamental Frequency Equation for a String

- $$\mu$$ is the linear mass density of the string
For a vibrating string, the fundamental frequency equation is: Where:

Step 4:
: Fundamental Frequency Equation for an Air Column

- $$L$$ is the length of the air column
For an open-ended air column, the fundamental frequency is: Where:

Final Answer

1. For a string: f_{1} = \frac{1}{2L} \sqrt{\frac{T}{\mu}} 2. For an open-ended air column: f_{1} = \frac{v}{2L}
