An extended object is placed at the principal focus of a lens. Where will the final image be formed? Comment on the nature of the image.

To find the image - distance for varying object - distance in the case of a convex lens, a student obtains on screen a sharp image of a bright object placed very far from the lens. After that the gradually moves the object towards the lens and each time focuses its image on the screen. (a) In which direction - towards or away from the lens, does he move the screen to focus the object ? (b) What happens to the size of the image - Does it increase or decrease ? (c ) What happens when he moves the object very close to the lens ? (d) What happens to the intensity of the image as the object moves farther and farther away from the convex lens ?

A convex lens forms a real image of the object when the lens is at a distance of 1 m from the object. The size of the image is 3 times that of the object. The position of the object and the screen are kept fixed but the distance of lens from the object is doubled. The image is now one half of the size of the object, the focal length of the lens is

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
