A thin convergent glass lens `(mu_g=1.5)` has a power of `+5.0D.` When this lens is immersed in a liquid of refractive index `mu_1,` it acts as a divergent lens of focal length `100 cm.` The value of `mu_1` is

`5/3`

`4/3`

`5/4`

`6/5`

Text Solution

Verified by Experts

The correct Answer is:

`f_(1)/f=(mu-1)/(mu/mu_(1) -1)`
