Study Notes
Pre-Fishing Pole Era
- People used spears to catch fish before the invention of fishing poles.
Challenges of Spear Fishing
- Aiming directly at a fish with a spear would cause you to miss due to the refraction of light.
Refraction of Light
- The scientific term for the bending of light as it passes between air and water is refraction.
- Refraction occurs when light travels from one medium to another with a different optical density.
How We See Objects
- Light travels from objects to our eyes, allowing us to see them.
Refraction and Underwater Objects
- Refraction of light makes objects underwater appear closer than they actually are due to the bending of light as it passes from water to air.
- This phenomenon is responsible for the illusion of objects being closer than they are when viewed underwater.
