A student focuses the image of a well illuminated distant object on a screen using a convex lens. After that he gradually moves the object towards the screen and each time focusses its image on the screen by adjusting the lens .
1)in which direction does he move the lens ?
2)what happens to the image when he moves the object very close to the lens?

actually the image disappears on convex mirror
it is a property of convex lens when it is moved nearer image disappears
and the focal length goes infinite may be in downwards or upwards
eventually the object came nearer

He moves the lens towards the screen as the distance increases b/w the lens and object tje image formation will be much nearer to the lens which is the screen
The image is enlarged, u have edited the question he moves the object towards the lens not the screen anyway the answer is same for both
