Draw a rays diagram showing the image formation by a convex lens when an object is placed?
at the focus of the 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.

Draw a diagram to illustrate spherical aberration in a convex lens.

Draw a ray diagram to show the image formation by a simple microscope. What is the nature of the image formed?

By giving sign-conventions, derive the lens formula relating object distance, image distance and focal length for a thin convex lens. Draw a ray diagram to show the formation of image of an object placed between optical centre and focus of a convex lens.

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

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.
