The convex surface of a thin concavo-convex lens of glass of refractive index 1.5 has radius of curvature 10 cm. The concave surface has a radius of curvature 30 cm. The convex side is silvered and placed on a horizontal surface. Then where should a pin be placed on the optic axis such that its image is formed at the same place?

After cataract operation, a person is recommended with concave - convex, spectacles of curvatures 10 cms and 50 cm. Crown glass of refractive indices (1.51) for red and (1.53) for violet colours is used for this. Calculate the lateral chromatic aberration occurring due to these glasses.

In a biprism experiment, the eye piece is kept at a distance of 1.5 m from the slit and the distance of the 2nd dark band from the central point was found to be 1.2 cm. The sizes of the magnified and diminished images of slits produced by the convex lens are found to be 2.4 cm and 60 cm respectively. Calculate the wavelength of light used.

A point object ‘O’ is placed on the axis of a cylindrical piece of glass of refractive index 1.6 as shown in the figure. One surface of the glass piece is convex with radius of curvature 3 mm. The point appeared to be at 5 mm on the axis when viewed along the axis and from right side of convex surface. The distance of the point object from the convex surface is

A point object is kept 10 cm away from one of the surfaces of a thick double convex lens of refractive index 1.5 and radii of curvature 10 cm and 8 cm. Central thickness of the lens is 2 cm. Determine location of the final image considering paraxial rays only
