One face of an equiconvex lens of focal length 60cm made of glass (mu=1.5) is silvered. Does it behave like a convex mirror or concave mirror? Determine its focal length.

One face of an equiconvex lens of focal length 60cm made of glass (mu=1.5) is silvered. Does it behave like a convex mirror or concave mirror? Determine its focal length.

A plano-convex lens when silvered ono the plane side behaves like a concave mirror of focal length 60 cm. However, when silvered on the convex side, it behaves like a concave mirror of focal length 20cm. Then, the refractive index of the lens is

A plano-convex lens when silvered in the plane side behaves like a concave mirror of focal length 30 cm. However, when silvered on the convex side it behaves like concave mirror of focal length 10 cm. Then the refractive index of its material will be:
