Question

Why is it difficult to shoot a fish swimming in water ?​

Answer 1

It is difficult to shoot a fish swimming in water because due to the refraction at water and air interface, the fish appears to be raised, and seems to be close to the surface this is called 'apparent depth'. The shooter aims the gun at apparent position of the fish, instead of real position.

Answer 2

Due to a phenomenon called normal shift, the fish appears to be higher in water than it actually is ........a result of occuring refraction.

Also, the ripples in water make it had to spot the fish at a particular position.

hope this helps
