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