Class Responce:Electromagnetic Spectrum

In class we have been studying the electromagnetic spectrum. All electromagnetic waves travel at the same speed in a vacuum, but they have different wavelengths and different frequencies. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all part of this spectrum. In class we had this project where we were assigned a electromagnetic wave. I recieved the infrared wave. Infrared waves can be used in heat lamps, night vision, infrared cameras, thermograms, and ect. We made an advertisment to show what our waves can do. According to Nasa's Imagine the Universe, the spectrum is made of different waves of radiation.  The hotter and more energetic an object or event is can create a higher radiation then colder objects. http://imagine.gsfc.nasa.gov/docs/science/know_l1/emspectrum.html  I think it is important to understand the electromagnetic spectrum because it has already led us to very useful inventions and it could certainly bring more.
