Diverging lens -

If f is negative

- wherein

Happens when \left ( \mu -1 \right ) & \left ( \frac{1}{R_{1}}-\frac{1}{R_{2}} \right ) are of opposite sign.

 

 A convex lens behaves as diverging lens if a refrative index of outside medium is greater than that of lens.

\therefore \mu _{2}>\mu

\mu=\mu2

Incorrect

Option 2)

\mu<\mu2

Correct

Option 3)

\mu>\mu2

Incorrect

Option 4)

\mu\leq \mu2
