Describe with the help of a ray-diagram, the formation of image of a finite object placed in front of a convex lens between f and 2f. Give two characteristics of the image so formed.

Descibe with the help of a ray diagram the nature, size and position of the image formed when an object is placed in front of a convex lens between focus and optical center. State three characteristics of the image formed.

Draw a ray diagram to show image formation by a concave lens.

Draw a ray diagram to show the formation of the image of an object placed between the optical centre and focus of a convex lens. Deduce the relationship between object distance, image disatnce and focal length of lens.

Draw a labelled ray diagram to locate the image of an object fromed by a convex lens of focal length 20 cm when the object is placed 30 cm away from the lens.
