(a) between focus and twice the focal length of the lens
(b) beyond twice the focal length of the lens

Draw ray 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 ray diagram showing the image formation by a concave lens when an object is placed at the focus of the lens.

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

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 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 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 OR Draw the ray diagram when the object is kept between F_(1) and 2F_(1) of the convex lens. With the help of the diagram mention the position and nature of the image formed. [ F_(1) : Principal focus of the lens] (c ) at twice the focal length of the lens (d) at infinity (e ) at the focus of the lens
