Fundamental frequency and tension: Set the string length to $30cm$ and place a total mass of $50g$ on the end. Vary the frequency until you observe the fundamental frequency $f_1,$ and record this value. Repeat this procedure while increasing the load mass on the string in intervals of $50g$ up to a total mass of $400g.$

The tension on the string could be calculated by multiplying the mass values by the acceleration due to gravity $(9\mathrm{.}81\frac{m}{s^2}).$ However, it's not necessary to do this since the acceleration of gravity is a constant in the experiment. The relationship between $f_1$ and $T$ can be deduced by graphical analysis of $f_1$ versus load mass $m.$

For example, a plot of $f_1$ verses $m$ on linear paper will reveal whether the relationship is linear. If it is not linear, a log$-$log plot should be made to deduce the power relationship. The leading coefficient will include the acceleration of gravity, raised to the power you have deduced. I want to know how to do Calculationc and the graph$(2*2$log log$)$ even if it is fake number
