Draw ray diagrams to show the formation of images when the object in front of a convex mirror is
at any other position near the mirror.

A convex lens of focal lenght 20 cm is placed coaxially wih a convex mirror of radius of curvature 20 cm.the two are kept at 15 cm apart.A point object lies 60 cm in front of the convex lens.Draw a ray diagram to show the formation of the image by the combination.Determine the nature and position of the image formed.

The image of an object formed by a convex mirror is always…..

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 image formation when the concave mirror produces a real, inverted and magnified image of the object.

Draw a ray diagram to show image formation in a compound microscope. Find expression for its magnifying power.

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.

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.

When the image formed by a concave mirror is at infinity then what is the position of the object?
