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.

Describe with the help of a ray diagram the nature, size and position of the image formed when an object is placed at infinity (considerable distance) in front of a convex lens. State three characteristics of the image so formed.

Describe with the help of a ray-diagram, the size, nature and position of the image formed by a convex lens when an object is placed beyond 2f in front of the lens.

Draw ray diagram to show the image formation of image when object is placed in front of a concave mirror between pole and focus.

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.

Describe the position, nature and size of the image formed when the object is at Infinity on left of the convex lens

Draw the ray diagram and write the characteristics of the images formed when an object is placed. At infinity in front of a concave mirror.

With the help of a ray diagram, determine the position, nature and size of the image formed of an object placed at the centre of curvature of a concave mirror.

Calculate the position of the image of an object when placed at (a) focus of a convex lens. (b) focus of a convex lens.

If an object is placed at the focus of a convex lens, where is the image formed?
