Why is it that the birds flying in the sky do not cast their shadow on the earth ? |
|
Answer» We do not see the shadow of a bird flying high up in air because in their shadow, the umbra is absent and the penumbra is too large and too faint that it is not visible as the distance of screen (i.e. earth) is very large from the object (i.e. bird). |
