Question

The power of a thin convex lens ${ } _ { a } \mu _ { l }$ will be

Answer 1

Solution

By using ;

where ${ } _ { l } \mu _ { g } = \frac { \mu _ { g } } { \mu _ { l } } = \frac { 1.5 } { \mu _ { l } }$ and $f _ { a } = \frac { 1 } { P } = \frac { 1 } { 5 } m = 20 \mathrm {~cm}$

⇒ $\mu _ { l } = 5 / 3$
