Answer

$d_i=-170cm$ $m=-1.76$

Work Step by Step

$\frac{1}{f}=(n-1)\big(\frac{1}{R_1}-\frac{1}{R_2}\big)$ $f=\frac{1}{n-1}\frac{R_1R_2}{R_1+R_2}=\frac{1}{0.52}\frac{(-22cm)(18.5cm)}{-22cm+18.5cm}=223.6cm$ $d_i=\frac{1}{\frac{1}{f}-\frac{1}{d_o}}=\frac{1}{\frac{1}{223.6cm}-\frac{1}{96.5cm}}=-170cm$ $m=\frac{d_i}{d_o}=\frac{-170cm}{96.5cm}=-1.76$
