What is fiber optics?
Name three instruments that help us see very small objects or objects far way away.
1. Light
2. 300,000 m / s
3. Optics is the branch of physics that studies the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behavior of visible, ultraviolet, and infrared light.
4. Fiber optics (optical fibers) are long, thin strands of very pure glass about the diameter of a human hair. They are arranged in bundles called optical cables and used to transmit light signals over long distances. Hundreds of thousands of these optical fibers are arranged in bundles in optical cables.
1. Telescope
2. Microscope
3. Magnifying glass.
