Physics - Geometrical Optics Question with Solution | TestHub

In an experiment with a convex lens. The plot of the image distance$\left(v^{\text{'}}\right)$against the object distance$\left({\mu }^{\text{'}}\right)$measured from the focus gives a curve$v^{\text{'}}{\mu }^{\text{'}}=225$. If all the distances are measured in$\mathrm{cm}$. The magnitude of the focal length of the lens is _____$\mathrm{cm}$.
