JCE Classroom Activity
Investigating the Invisible: Attenuation of Radio Waves
Anthony A. Smith and Charles A. Smith
Department of Chemistry, Our Lady of the Lake University, San Antonio, TX 78207

April 2005
Vol. 82 No. 4
p. 560A
Abstract
Students often think of light as only being the visible region of the electromagnetic spectrum. It is often difficult for students to visualize the electric and magnetic fields that compose light and that different frequencies of light have different wavelengths. This Activity helps students to investigate these concepts in an interactive and novel fashion. In this Activity, students investigate properties of radiation using a handheld radio. Students compare the abilities of conductive and dielectric materials to attenuate, or block, radio waves, and compare the attenuation of AM vs. FM radio waves.
