Question

A concave mirror forms a real image at a distance of 25 cm for an object distance of 50 cm. Calculate the focal length of the mirror and its radius of curvature. Calculate the magnification produced by the mirror

Answer 1

$$\begin{gathered} DearStudent, \\ Herev=25cm \\ u=50cm \\ asweknow \\ \frac{1}{v}-\frac{1}{u}=\frac{1}{f} \\ \frac{1}{f}=\frac{1}{25}-\frac{1}{50} \\ f=50cm \\ asweknowalsoRadiusofcurvatureC=2f \\ soC=2\times 50=100cm \\ magnification \\ m=\frac{v}{u}=\frac{25}{50}=\frac{1}{2} \\ Regards \\ Regards \end{gathered}$$
