What will be the effect on the focal length and nature of a lens when immersed in a liquid, whereas the liquid...

What will be the effect on the power of a glass lens if it is immersed in water ?

What happens to focal length of a convex lens when it is immersed in water ?

Focal length of a convex lens of refractive index 1.5 is 2 cm. Focal length of lens when immersed in a liquid of refractive index 1.25 will be

Focal length of a lens in air is f. Refractive index of the lens is mu . Focal length changes to f_(1) if lens is immersed in a liquid of refractive index (mu)/(2) and it becomes f_(2) if the lens is immersed in a liquid of refractive index 2 mu . Then

A biconvex lens of refractive index "1.5" has a focal length of "20cm" in air.Its focal length when immersed in a liquid of refractive index "1.6" will be:

A thin lens made of a material of refractive index mu_(0) has a focal length f_(0) in air. Find the focal length of this lens if it is immersed in a liquid of refractive index mu .
