Shown in the figure here is a convergent lens placed inside a cell filled with a liquid. The lens has focal length +20cm when in air and its material has refractive index 1.50. If the liquid has refractive index 1.60, the focal length of the system is a sphere of the same radius but of [...]

A luminous object is placed at a distance of 30 cm from the convex lens, of focal length 20 cm. On the other side of the lens, at what distance from thelens a convex mirror of radius of curvature 10 cm be placed in order to have an image of the object coincident with it [...]

A point object O is placed on the principal axis of a convex lens of focal length f=20cm at a distance of 40 cm to the left of it. The diameter of the lens is 10. An eye is placed 60 cm to right of the lens and a distance h below the principal axis. [...]
