what happens to the shadow formed on screen when the distance between the source light and the object increases and the distance between the object and the screen decreases
The shadow will get smaller as the distance increases, and will get bigger as the distance decreases. This is because of narrower angular projection of the shadow when the object is farther vs wider angle of projection when the object is closer.
