A convex lens of glass has power P in air. If it is immersed in water its power will be

A convex lens of glass ( mu = 1.5) is immersed in water. Compared to its power in air, its power in water-

A convex lens of power P is immersed in water. How will its power change ?

A convex lens (refractive index mu = 1.5) has a power P. If it is immersed in a liquid ( mu = 4/3), then its power will become/remain

A convex lens (refractive index mu = 1.5) has a power P. If it is immersed in a liquid ( mu = 4/3), then its power will become/remain

Assertion : If a convex lens of glass is immersed in water its power decreases. Reason : In water it behaves as a convex lens.

Assertion : If a convex lens of glass is immersed in water its power decreases. Reason : In water it behaves as a concave lens.

A lens has a power of +5 D in air.If completely immersed in water,what will be its power ?Given,refractive index of glass = 3//2 ,refractive index of water = 4//3 .

The power of a thin convex lens of glass is 5 dioptre . When it is immersed in a liquid of refractive index mu , it behave like a diverging lens of focal length 1m . Calculate mu of liquid, if mu of glass = 3//2 .
