Draw the ray diagrams and find position,nature and size of image formed by a convex lens,when object is placed: between F and 2F

Draw the ray diagrams and find position,nature and size of image formed by a convex lens,when object is placed:At F.

Draw the ray diagrams and find position,nature and size of image formed by a convex lens,when object is placed: beyodn 2 F

Give the nature, position and size of the image formed by a convex lens when the object lies at 2 F

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

Draw a ray diagram to show the image formation by a concave mirror, when the object is kept between its focus and the pole.

A concave mirror forms image inverted and equal in size, when object is placed at…… .

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.

Describe with the help of diagram the natrue, size and position of the image formed when and object placed at centre of curvature of a concave mirror.

An object is placed exactly midway between a convex and concave mirror each of focal length 15 cm.The two mirror are placed 60 cm apart and the two mirrors face each other.Find the nature and position of the image formed by reflection first at convex and then at the concave mirror.
