If a man shoots a spear at a place where he sees the fish inside water ,is it possible that it will hit the fish? write with fast

No, he wouldn’t hit it because when light hits water, the light refracts, meaning that it bends. This allows objects to look like they are in one place while in reality, it is in a different location not too far away. If you have ever seen a straw in a glass, you can see that the water refracts the shape of the straw making the straw look like it is snapped in half.
