A diverging lens of glass (μ = 1.5) has both surfaces of the same radius of curvature (R). On immersion in a medium of refractive index (μ = 1.8), it will behave as |
diverging lens with focal length f = 3R diverging lens with focal length f = 0.3R Converging lens with focal length f = 3R Converging lens with focal length f = 6R |
Converging lens with focal length f = 3R |
The correct answer is Option (3) → Converging lens with focal length f = 3R |
