1.	the image of a well illuminated distant object on a screenusing a convex lens. After that he gradually moves the object towards the lens andQ.5.Astudentfocusseseach time focusses its image on the screen by adjusting the lens.i) In which direction, towards the screen or away from the screen, does hemove the lens ?(i) What happens to the size of the image? Does it decrease or increase?ii) What happens to the image on the screen when he moves the object veryclose to the lens?
Answer» (a) As the object is moved towards the lens, the image distance increases. Thus, the student moves the lens away from the screen to focus the image. (b) Size of the image increases when the object is moved towards the lens. (c) When the object is moved very close to the lens, no image is formed on the screen. A virtual image is formed behind the object on the same side of the screen. Like my answer if you find it useful!

(a) As the object is moved towards the lens, the image distance increases. Thus, the student moves the lens away from the screen to focus the image.

(b) Size of the image increases when the object is moved towards the lens.

(c) When the object is moved very close to the lens, no image is formed on the screen. A virtual image is formed behind the object on the same side of the screen.
