Answer

\frac{L^2 - d^2}{4L} $into the form$ Y = mX + C$.

To determine the focal length $f$ using a graph, we need to linearize the given equation $f = \frac{L^2 - d^2}{4L}$ into the form $Y = mX + C$ .

Step 1: Rearrange the equation. Multiply both sides by $4L$ : $4Lf = L^2 - d^2$

Step 2: Identify variables for plotting. To obtain a linear graph $Y = mX + C$ , we can set: $Y = L^2 - d^2$ $X = 4L$ The equation then becomes: $Y = fX$ This is a linear equation where the y-intercept $C=0$ and the slope $m$
