By the end of this section, you will be able to define antinode, node, fundamental, overtones, and harmonics; identify instances of sound interference in everyday situations; describe how sound interference occurring inside open and...

By the end of this section, you will be able to define intensity, sound intensity, and sound pressure level and to calculate sound intensity levels in decibels (dB).

A physics tutorial on designing an auditorium and solving the problem of sound reflection. Illustrated.

Study the details of sound from characteristics to speed, ultrasound, infrasound, and other aspects of sound waves.

The concept of pitch and frequency is covered in this tutorial. Learn what frequency and pitch are, the difference between infra sound and ultrasonic frequencies, and how pitch is related to the frequency of a sound.

Information about the interference of sound and its causes. Well-illustrated and good explanations of the concepts; part of a large hyper-textbook on various physics concepts.

Here is described a simple process to 'put a voice on a sunbeam' and transmit it over a distance. It is a fascinating example of amplitude modulation of light using sound vibrations. It then describes how the modulated light is detected...
