Suggestions and demonstrations for a unit on wave theory for a high school physics class

Abstract

Scope of Study: This report contains a partial development of a unit on wave theory with emphasis on the basic similarities of all wave motion. Some of the topics which are included in the unit are: simple harmonic motion, transverse and longitudinal waves, Huygens' Principle, diffraction and interference, reflection, refraction, polarization, and Doppler effect. Demonstrations are given which will aid in the teaching of these topics and emphasis is placed on the use of a variety of demonstrations from the various types of wave motion. The report also gives suggestions about some of the methods of presentation which can be used with certain topics.

Findings and Conclusions: Since this report has not been used in the actual teaching situation, the conclusions reached are only the desired results which the writer feels should be aimed for in the teaching of the unit. One of the advantages of teaching wave theory by this method is the saving of time as a result of unification of the material. Another desired outcome would be that the students would have a clearer understanding of the interrelationship between the various sections of physics and would see physics as a unified science. The writer feels that this unification of material which has been done in this report needs to be done in other areas of physics.
