Lens With One Silverd Surface

An object is placed at a distance of 20cm from a equi-concave lens of focal length 30cm , whose one surface is silvered. If the radius of curvature of the silvered surface is 60cm , find the position and nature of the image.

One side of radius of curvature R_2=120 cm of a convexo-convex lens of material of refractive index mu=1.5 and focal length f_1=40 cm is slivered. It is placed on a horizontal surface with silvered surface in contact with it. Another convex lens of focal length f_2=20 cm is fixed coaxially d=10 cm above the first lens. A luminous point object O on the axis gives rise to an image coincide with it. Find its height above the upper lens.

A lens has one concave surface of R_(1) = 2 m and convex surface with R_(2) = 3 m then focal length of lens is(if refractive index of the lens is 3/2)

Plane surface of a thin plano-convex lens is silvered. If a point object is placed on principal axis at a distance 60cm from the lens and fial image is formed at a distance 30cm from the lens on same side. What will be the distance of final imagge from the lens if the plane surface is not silvered.

A plano-convex lens has a maximum thickness of 6 cm. When placed on a horizontal table with the curved surface in contact with the table surface, then the apparent depth of the bottom most point of the lens is found to be 4 cm. If the lens is inverted such that the plane face of the lens is in contact with the surface of the table, then the apparent depth of the centre of the plane face is found to be 17/3 cm. The radius of curvature of the lens is

The focal length of plano-convex lens, the convex surface of which is silvered is 0.3m , if mu of the lens is 7//4 , the radius of curvature of the convex surface is

There is a thin double convex lens having surfaces of radius of curvature R and 2R. Lens is kept in air and refractive index of the material of the lens is mu . Focal length of the lens

A thin converging lens is formed with one surface convex and the other plane. Does the position of image depend on whether the convex surface or the plane surface faces the object ?

Determine the focal length of a concave spherical mirror which is manufactured in the form of a thin symmetric biconvex glass lens one of whose surfaces is silvered. The curvature radius of the lens surface is R = 40 cm .
