An object is placed in front of a convex lens of focal length 12 cm. If the size of the real image formed is half the size of the object, calculate the distance of the object from the lens.

An object is placed in front of a convex mirror of focal length 60 cm. If image formed is half the size of the object, the position of the image

A convex lens of focal length 16 cm forms a virtual image of double the size of the object. What is the distance of the object from the lens ?

An object of length 2.0 cm is placed perpendicular to the principal axis of a convex lens of focal length 12 cm. Find the size of the image of the object is at a distance of 8.0 cm from the lens.

An object of length 2.0 cm is placed perpendicular to the principal axis of a convex lens of focal length 12 cm. Find the size of the image of the object is at a distance of 8.0 cm from the lens.

An object is placed at a distance 24 cm in front of a convex lens of focal length 8 cm. Calculate the distance of the image from the lens.

A convex lens of focal length 16 cm forms a real image double the size of the object. The image distance of the object from the lens is
