An object is placed between F and 2F of a convex lens. The image formed is real, inverted and diminished.

An object is placed at a distance of f//2 from a convex lens .The image will be

Draw a ray diagram to show how the image is formed when the object is placed between f and 2 f distances from a convex lens.Deduce the relation between the distances of he oject and the image from the lens and the focal length of the lens under this condition.

An object is placed in front of a convex mirror of focal length 30 cm.If the image formed is a quarter of the size of the object,find the position of the image.

Use the mirror equation to deduce that: an object placed between f and 2f of a concave mirror produces a real image beyond 2f.

Two lenses convex lens of focal length 30 cm in contact with a concave lens of focal length 20 cm, if they are placed 8.0 cm apart with their principal axes coincident. An object 1.5 cm in size is placed on the side of the convex lens. The distance between the object and the convex lens is 40 cm. Determine the magnification produced by the two-lens system, and the size of the image.

What is minimum distance between an object and the real image formed by a convex lens?
