Draw a rays diagram showing the image formation by a convex lens when an object is placed?
between focus and twice the focal length 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 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.

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 a diagram to illustrate spherical aberration in a convex lens.

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: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

A screen is placed 90cm from an object. The image of the object on the screen is formed by a convex lens at two different locations separated by 20cm. Determine the focal length of the lens.

The image of a candle is formed by a convex lens on a screen. The lower half of the lens is painted black to make it completely opaque. Draw the ray diargram to show the image formation. How will this image be different from the one obtained when the lens is not painted black?
