EM Spectrum Reflection
The EM Spectrum is what scientists use to categorize the different kinds of radiation. Scientists usually study EM radiation from space because the Earth's atmosphere blocks most of the rays from coming to Earth. However, there is no atmosphere in space, so scientists can easily study the rays where they can be accurately observed. I liked learning about photons, which are massless particles with properties of both waves and particles. I also learned that night vision goggles use infrared radiation to see at night. It makes me want a pair of them! I also learned that gamma rays can kill, and not just turn people into the incredible hulk. I still want to know if there are things longer than radio waves that we just cannot observe, and i also want to know if there is anything shorter than a gamma ray that we also cannot observe. I liked the freedom to organize out newsletter as we chose, but I didn't like that some of the questions were ambiguous. if i would change anything, i would change how the questions were worded.
