Assertion : If a convex lens of glass is immersed in water its power decreases. Reason : In water it behaves as a concave lens.
A convex lens of glass ( mu = 1.5) is immersed in water. Compared to its power in air, its power in water-
If a convex lens is immersed in water, then its focal length
A convex lens of glass has power P in air. If it is immersed in water its power will be
Radius of curvature of two surfaces of a glass convex lens is 20cm each. If refractive index of glass is 3//2 , what is the power of lens in D ?
A glass convex lens of refractive index 3/2 has got a focal length equal to 0.3 m. Find the focal length of the lens if it is immersed in water of refractive index 4//3 .
The power of a lens kept in air is P. When it is immersed in water, then power becomes ( mu _(water) =4/3, mu_(Lens) = 3/2 )
