1. Watch the video titled "What Are Gamma Rays?" (1 min 39 sec) under the Gamma Rays terms section of the Science Corner. You can also view the video at https://www.youtube.com/watch?v=PPlrtgilgK8. Next, give your opinion on whether or not the benefits of space exploration to the Moon and Mars outweigh the risks and costs of exposing such travelers to gamma rays above Earth's atmosphere. Provide a rationale for your response.
2. Watch the video titled "Video Tour of the Electromagnetic Spectrum" (5 min 3 sec) under the EM Spectrum terms section of the Science Corner. You can also view the video at https://missionscience.nasa.gov/ems/emsVideo_01intro.html. Next, describe one to two (1-2) ways that you encounter and utilize electromagnetic radiation in your daily life. Note: Feel free to include both naturally occurring examples, as well as any man-made technologies.
3. Choose a technology device that makes use of the EM Spectrum. Next, explain how this device works using terminology learned in this chapter.
Please explain why the emission of the electrons doesn’t occur when the wavelength of incident radiation is set to the maximum value (for example 799.9 nm for lead)?
