Light
Light is a kind of electromagnetic radiation. It is made up of vibrations between a certain group of frequencies. When light is given off from a source it spreads out over a larger area. Scientists are still dumbfounded by exactly what light is. When light hits a smooth or polished surface it "bounces" off at the same angle that it hit. Reflecting telescopes are made of concave mirrors and they have helped astronomers chart the universe because the mirrors interact with each other to magnify what is being observed. Refraction is when light bends as it goes through glass, water and other transparent objects that are denser than air. A prism is an instrument that spreads out a ray of light into the color spectrum. A lens is another instrument that uses the light refraction, but lenses are put to more practical uses (I’m not saying that a mirror isn’t practical enough.). ______________________________________________________________________ Welcome to the wonderful world of light, including the refraction and reflection of light. Refraction is the bending of light when it travels through a denser, or thicker material, such as water. Reflection is a bit different though; when light hits a smooth or polishe
