Question

.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 1

Answer:

Explanation:

While the football is placed on the ground their shadow can be seen.

Here the ground acts as the mirror or the screen for the shadow to fall.

But when the football is kicked up, the ball is in the air and is high up.

Then the ground stops acting as screen.

Hence the shadow of the football will not be formed when it is high up

Answer 2

Answer:

The shadow of the football cannot be seen when it is kicked high in the air because the umbra is so small that it disappears in the air and a faint penumbra falls on the Earth that cannot be seen by our eyes. This is why we also cannot see the shadow of a flying bird or an aeroplane.
