Standing Sound Waves definitions Flashcards

Waves where particle displacement is parallel to wave direction, typical in sound waves.

Waves where particle displacement is perpendicular to wave direction, typical in strings.

Waves that remain in a constant position, formed by interference of two waves traveling in opposite directions.

A pipe with both ends open, where standing waves have antinodes at each end.

A pipe with one end closed, where standing waves have a node at the closed end and an antinode at the open end.

A point in a standing wave with maximum amplitude, occurring at open ends of pipes.

A point in a standing wave with zero amplitude, occurring at closed ends of pipes.

The lowest frequency at which a system oscillates, corresponding to n=1.

Frequencies that are integer multiples of the fundamental frequency.

Any frequency higher than the fundamental frequency, often referred to by its order.

The speed at which sound waves travel through a medium, typically 343 m/s in air.

For open pipes: nv/2L; for closed pipes: nv/4L, where n is harmonic number.

For open pipes: 2L/n; for closed pipes: 4L/n, where n is harmonic number.

Numbers like 1, 3, 5, etc., used for harmonic numbers in closed pipes.

The fourth harmonic in open pipes, seventh harmonic in closed pipes.
