A biconvex thin lens is prepared from glass `(mu=1.5)`, the two bounding surfaces having equal radii of 25 cm each. One of the surfaces is silvered from outside to make it reflecting. Whee should an object be placed before this lens so that the image is formed on the object itself?

A biconvex thin lens is prepared from glass of refractive index 3//2. The two bounding surfaces have equal radii of 25cm each. One of the surfaces is silvered from outside to make it reflecting. Where should an object be placed before this lens so that the image coincides with the object.

A biconvex thin lens is prepared from glass of refractive index mu_(2)=(3)/(2) . The two conducting surfaces have equal radii of 20 cm each. One of the the surface is silvered from outside to make it reflecting. It is placed in a medium of refractive index mu_(1)=(5)/(3) . It acts as a
