Does the Material Transmit EM Waves or Shield a Detector from a Source of EM Radiation?
Janet Landato, Harper College This presentation is part of an interactive demonstration that was used in an astronomy class. The source of EM radiation is an FM radio station. The detector is a portable radio. Common materials such as plastic serve as potential shields. The demonstration is an introduction to the topic of the electromagnetic spectrum and modern multi-wavelength astronomy. A NASA poster on electromagnetic radiation suggested this activity. Participants will receive copies of a prediction grid.
