It doesn't help at all. It makes it more difficult, because if you're out in the air,
then underwater objects are not in the direction they appear to be. You must
make a correction before you loose your spear, and aim it at a place where the
fish appears not to be.
Refraction can help spearfishers by making fish appear closer to the surface than they actually are. This can make it easier to accurately aim and spear the fish, as the refraction bends the light and distorts the fish's apparent position. By understanding how refraction works underwater, spearfishers can compensate for the distortion and improve their chances of a successful catch.

How do you allow refraction when spear fishing?
To allow for refraction when spearfishing, you need to compensate for the way light bends as it moves between water and air. Aim slightly lower than the actual location of the fish to adjust for the bending of light, allowing you to effectively target your prey. Practice and experience will help you hone your skills in accounting for refraction while spearfishing.
What is it called when a wave goes from one medium to another and it changes speed and direction?
It is called refraction. Refraction occurs when a wave changes speed and direction as it travels from one medium to another, due to the change in its wave velocity and the change in the medium's optical density.
Does the eye use refraction?
Yes, the eye uses refraction to focus light onto the retina so that we can see clearly. The cornea and lens in the eye help to bend light rays to create a clear image on the retina.
How does the angle of refraction change as the index of refraction of the bottom material increases?
As the index of refraction of the bottom material increases, the angle of refraction will decrease. This relationship is governed by Snell's Law, which states that the angle of refraction is inversely proportional to the index of refraction. Therefore, higher index of refraction causes light to bend less when entering a denser medium.
How do you think increasing a medium's index of refraction might affect the angle of refraction?
Increasing the medium's index of refraction will cause the angle of refraction to decrease. This is because light bends more towards the normal as it enters a medium with a higher index of refraction.
Is spearfishing hard with refraction?
Yes, spearfishing can be more challenging due to refraction, which distorts the appearance and position of fish underwater. It may require the spearfisher to aim slightly lower than where they see the fish in order to make an accurate shot. Practice and experience can help in adjusting for refraction to improve success in spearfishing.
