Through inquiry, learners will use various objects/materials attached to strings to investigate how vibration causes sounds waves.

Review the characteristics of periodic transverse and longitudinal waves such as wavelength, crest, trough, amplitude, expansion, and compression.

Students see illustrated diagrams and animations to help them understand the pressure characteristics of a sound wave.

Students explore and discover how sound is created through longitudinal waves.

Test yourself on the topics of identifying the characteristics of a longitudinal or transverse wave such as the wavelength, crest, and areas of compression with this multiple choice quiz.

[Free Registration/Login may be required to access all resource tools.] What a longitudinal wave is, its compressions and rarefactions and what a P wave is.

Sound is defined and characterized as a wave consisting of oscillations in pressure of a medium. Includes graphics and links to further information.

Through multiple animations and interactive activities, this module allows students to investigate the properties of sound.

Link to nine major physics topics and dig deeper into the content. Find out about the work of scientists in each field and see example physical science experiments.

Physics tutorial on measuring the speed of sound in dry air. An interactive form allows the student to practice solving problems involving the temperature dependence of the speed of sound.
