Review of how to produce beats through the constructive and destructive interference of sound waves.

Use this interactive physics tutorial to introduce students to the concepts of pitch and frequency in sound waves.

With videos, illustrated diagrams, and informational text, students learn about sound waves as forced vibrations.

Through animations, videos, and text, students discover that all objects have a natural frequency or set of frequencies at which they vibrate.

The focus of this physics tutorial is on the application of mathematical relationships and standing wave concepts to musical instruments in three general categories of instruments: instruments with vibrating strings, open-end air column...

Illustrated diagrams and interactive practice problems show constructive and destructive interference occurring at sound beats.

Elaborate on the essential characteristics and the causes of standing wave patterns and relate these patterns to the vibrations of musical instruments.

For musical instruments and other objects that vibrate in regular and periodic fashion, the harmonic frequencies are related to each other by simple whole number ratios. Students learn why these whole number ratios exist for a musical...

A guitar string has a number of frequencies at which it will naturally vibrate. These natural frequencies are known as the harmonics of the guitar string. Students work through several example problems.

The animation portrays a medium as a series of particles connected by springs. In this type of longitudinal wave the particles of the medium vibrate in a direction parallel to the direction of energy transport.
