Draw a ray diagram in each of the following cases to show the formation of image, when the object is placed : between optical centre and principal focus of a convex lens.
With the help of a ray diagram, show the formation of an image of an object placed between principal focus and centre of curvature of a concave mirror.
Write two characteristics of image formed when an object is placed between the optical centre and focus of a thin convex lens. Draw the graph showing variation of image distance v with object distance u in this case.
Draw ray diagrams showing the image formation by a convex lens when an object is placed (a) between optical centre and focus of the lens (b) between focus and twice the focal length of the lens ( c) at twice the focal length of the lens (d) at infinity , (e) at the focus of the lens
Draw ray diagram showing the image formation by a convex lens when an object is placed at twice the focal length of the lens.
