Report on basic radio demonstrations for high school physics

Bruce, Wilburn Huel
Abstract
Scope of Study: In many high school and college physics courses, the units on radio and electronics have often been treated lightly or skipped entirely. With the field of radio and electronics becoming more important each day, the high school physics teacher should make a greater effort to present some of the important principles and applications of radio and electronics to the student. This report presents six demonstrations that cover the fundamental principles involved in radio transmission and reception. By the use of demonstrations to supplement the regular experiments, the principles and applications of electronics can be presented more effectively. Standard electronic circuits for the demonstration apparatus are drawn from basic texts in the field. Principles of rectification, oscillation, modulation and polarization of radio waves are demonstrated.
