Riddle: I’m the part of the bird that’s not in the sky. I can swim in the ocean and yet remain dry. What am I?
The answer of this riddle is a shadow. In a place where there is sunlight, one side of our body cuts off the incoming light. And the rest of it stays in the dark. Here is a shadow on the side where there is no light.
In other words, when light encounters anything that is not transparent, it cannot reach the back of that object, and that side remains in the dark. This area is called shadow. Think of the shadow of a bird. The bird flies in the air, its shadow is on the ground. But because the shadow is nothing concrete, it doesn’t get wet, even in the ocean.
The correct answer is: A shadow.
