A point object is placed at a distance of 20 cm from a thin plano-convex lens of focal length 15 cm. If the plane surface is silvered, the image will from at :- (A) 20cm cm from left of AB (B) 60 cm from left of AB (c)30 cm from left of AB (d)12 cm from left of AB 60 cm from right of AB

A point object is placed at a distance of 20 cm from a thin plano-convex lens of focal length 15 cm(mu=1.5). The curved surface is silvered. The image will form at

A point object is placed at distance of 20 cm from a thin plane - convex lens of focal length 15 cm . The plane surface of the lens is now silvered . The image created by the system is :-

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.

A point object is placed at a distance of 30 cm from a convex mirror of focal length 30 cm. The image will form at
