Transcript of Electromagnetic Spectrum

So there is this dohickey called the electromagnetic spectrum thing I've do to do for school This prezi is about the electromagnetic spectrum Bibliography IBI.gov, nasa.gov, ehow.com. ,daymail.co.uk ,bio-mat.com Science class notes I'm going to start with the gamma rays because they are dangerous. Gamma rays really just radioactive waves, and other forms of radiation. They are used to treat cancer. Next up are X rays they are what we think of them as. X rays. They penetrate flesh but not bone thus showing us if a bone is fractured or not. They give of radiation. Fun fact. For an object to see rays the waves must be around the same size as the object. Ultra violet waves are to small for the human eye to see some insects such as bees can see them. This is a ultraviolet sun. There are not many waves that go under visible rays in the spectrum so I wont dedicate much space to them. They are the light we see. Infrared waves can often penetrate deeply into bodies and warm them. Microwaves. They are basically really high frequency radio waves Radio waves are used in I pods MP3 players and radios to carry messages. The spectrum is a series of light waves that are used in day to day life. The waves go from radioactive gamma rays to the terribly weak radio waves. I'M DONE (: (: (: (: (: (: (:
