Question

If a spear is thrown at a fish swimming in a lake, it will often miss the fish completely. Why does this happen?

A.
A reflection of the fish appears on the surface of the water causing it to appear very shallow.
B.
The fish sees the light produced by the spear and knows which direction to move.
C.
The water diffracts the light causing three or more images of the fish to be seen.
D.
Refraction of light between the air and water causes the fish to appear in a different location..

Answer 1

D. Refraction of light between the air and water causes the fish to appear in a different location

Step-by-step explanation:

When you something in the water you see that the objects appear shallower or the real position and the apparent position differ. This happens due to refraction of light. Refraction is a phenomenon of light where it bends when it moves from one medium to another.

In this scenario when the observer looks at the fish, the position of the fish seen to the observer will be different than its actual position because of which the spear will miss the fish most often.
