A convex lens of focal length `20 cm` is placed co-axially with a convex mirror of radius of curvature `20 cm`. The two are kept `15 cm` apart from each other. A point object is placed `60 cm` in front of the convex lens. Find the position of the image formed by the combination.

A convex lens of focal length 20 cm is placed co-axially with a convex mirrir of radius of curvature 20 cm . The two are kept 15 cm apart from eachother. A point object is placed 60 cm in front of the convex lens. Find the position of the image formed by the combination.

A convex lens of focal length 20cm is placed coaxilly with a convex mirror of radius of curvature 20 cm. The two are kept 15 cm apart. A point object is placed 40 cm in front of the convex lens. Find the position of the image formed by this combination. Draw the ray diagram showing the image formation.

A convex lens, of focal length 25 cm, and a concave mirror, of radius of curvature 20 cm. are placed co-axially 4 cm aprat from each other. An incident beam, parallel to the principal axis, is incident on the convex lens. Find the position and nature of the image formed by this combination.

A convex lens of focal length 20 cm and a concave lens of focal length 15 cm are kept 30 cm apart with their principal axes coincident. When an object is placed 30 cm in front of the convex lens, calculate the position of the final image formed by the combination. Would this result change if the object were placed 30 cm in front of the concave lens ? Give reason.

A convex lens of focal length 15 cm , and a concave mirror of radius of curvature 20 cm are placed co-axially 10 cm apart. An object is placed in front of convex lens so that there is no parallax between the object and its image formed by the combination. Find the position of the object.

A convex lens of focal length 20 cm and a convex mirror of focal length 10 cm are placed co-axially 50 cm apart from each other. An incident beam parallel to its principal axis is incideent on the convex lens. Locate the position of final image formed due to the combination.

A convex lens of focal length 10 cm is placed coaxially 5 cm away from a concave lens of focal length 10 cm. If an object is placed 30 cm in front of the convex lens, find the position of the final image formed by the combined system.

An object placed 10 cm in front of a convex lens of focal length 15 cm. The image produced will be

A convex lens of focal length 20cm is placed 10cm in front of a convex mirror or radius of curvature 15cm. Where should a point object be placed in front of the lens so that it images on to itself?
