The electromagnetic spectrum is made up of six different types of waves. Radio waves, Microwaves, Infrared waves, Visible light, Ultraviolet light, X-rays and Gamma rays. The radio waves are used to transmit radio and television signals. The infrared waves are used to tell temperature of areas. Visible light is all the colors that we can see. Ultraviolet light can help things grow but to much can cause diseases such as skin cancer. X-rays are used as a tool to find broken bones or take pitchers of our sun. Gamma rays are used in medical science but they are often used to produce images of our universe. If you would like to know more about the spectrum keep reading.

The reason we can see all the colors we do is simple. The light of the world reflects off the objects giving it color. Such as when it is sunny out every thing the sun hits is more visible and we can see its color. The moon works the same way it's just less light making it harder to see the color. Now Im a scuba diver and when I go under water the last color I see is blue. The color of the water once under water I can no longer see color except for what little portion of the sun that peers down through the water giving every thing a grayish color. But when I bring a dive light down with me I can actually see every thing's color. Thats why swim wear is reflective so you can see it under the water or not. Ultraviolet radiation has a range of wavelengths from 400 billionths of a meter to about 10 billionths of a meter. Small amounts of ultraviolet radiation can help us do things such as helping the plants grow through the process of photosynthesis, but larger doses can cause diseases, like skin cancer. Ultraviolet wavelengths are used periodically throughout astronomical observatories, and some remote sensing. Observations of the earth are also concerned with the measurement of the ozone layer. The reason for that is that if we didn't have the ozone layer all of the Suns ultraviolet radiation would rain down giving us skin cancer and destroying all vegetation. X-rays are high energy waves
