Sound and ultrasound in educational research. Textbook: Mayer, Varaskina

The book contains descriptions of educational research related to the physics of elastic waves, which are recommended for the independent execution of high school students. Devices are offered to obtain high sound and low frequency ultrasound. The physical phenomena of linear and nonlinear ultraacousticism, the practical use of ultrasound are examined in detail. All experiments are available and can be set in a school physical office or at home. Conducting small experimental research, the reader will get acquainted with interesting and almost important phenomena of physics of elastic waves, will acquire independent work skills.
For teachers of physics of secondary and higher schools, heads of elective courses, physical and technical circles, as well as for persons engaged in self -education.
2nd edition.
