Light Visible And Invisible

Download or read book Invisible Universe written by Stephen M. Pompea and published by LHS GEMS. This book was released on 2002 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 5 class sessions, of 45-60 minutes each, deepen student understanding of the electromagnetic spectrum, enabling students to detect and consider wavelengths other than visible light. Activities feature energy stations, including infrared (TV remote); microwave (pager); ultraviolet (black light) and other devices. Students come up with their own tests to see what blocks each wavelength, and what does not. They learn how these other wavelengths can be used to "see" things we cannot see with our eyes.
