EM Spectrum Project

The EM Spectrum is is a chart that shows the different types of radiation, the colors each type corresponds with, and the wavelength of each type of radiation. Astronomers use the spectrum to look at different objects in space. With using a camera with certain types of radiation they can see different things about an object in space. They can see the heat of something or dust and clouds around an object. One concept that I learned was that there are different types of radiation in out every day lives. For example a microwave has microwaves in it. Another concept that I learned was that some waves can be very dangerous. For example Gamma rays in space. If a star has a Gamma ray burst then it can shoot off powerful gamma rays that basically destroy everything in its path. One question I still have about the EM Spectrum is how do they measure the waves? Another question that I have is how people can contain the waves? Like how people get microwaves in a microwave. My favorite thing about this project was making the newsletter. I liked how I had the freedom of putting everything where i wanted it to go. One thing that i did not like about this project was that there were a lot of websites. It got confusing at some points when i had all the websites up and i forgot which information was on which website. If i had to change one thing about this project it would be less websites.
