A football match is being played at night in a stadium with flood lights ON. You can see the shadow of a football kept at the ground but cannot see its shadow when it is kicked high in the air Explain.

Answer:

We can see the shadow of a football kept at the ground in flood lights because the ground of stadium acts as screen for it but one cannot see its shadow when it is kicked high in the air because here ground will not act as screen due to more distance between ground and football. If we take an object away from the screen, the image becomes smaller and ultimately, it disappears from the screen.
