List of top Physics Questions on spherical lenses asked in JIPMER

The plane face of a planoconvex lens is silvered. If $\mu$ be the refractive index and $R$, the radius of curvature of curved surface, then the system will behave like a concave mirror of radius of curvature

The power of biconvex lens is 10 dioptre and the radius of curvature of each surface is 10 cm. Then the refractive index of the material of the lens is

If the distance of the far point for a myopia pa dent is doubled, the focal length of the lens required to cure it will become:

A convex lens of focal length 0.5 m and concave lens of focal length 1 m are combined. The power of the resulting lens will be:

Two lenses of power +1.5 diopter and +1.0 diopter are placed in contact, the effective power of the combination is:
