Fundamental Frequency:

Frequency is known as the rate at which a vibration occurs per unit time or also known as the inverse of the period. The fundamental frequency is defined as the lowest frequency attained by an oscillating object.

Answer and Explanation:

The fundamental frequency is given by the expression

{eq}\displaystyle f = \frac{1}{2L} \sqrt{\frac{MgL}{m}} {/eq}

In this case,

  • {eq}L = 0.95\ \rm...
