Section 1

(23 cards)

natural frequencies

Front

the frequencies of waves necessary to produce resonance

Back

superposition

Front

The adding together of two or more waves to form a net disturbance

Back

sound intensity

Front

The sound power per unit that passes perpendicularly through a surface (W/m^2)

Back

Change the medium it travels in

Front

What is the only way to change the speed of a wave?

Back

Amplitude

Front

The maximum excursion of a particle of the medium from the particle's undisturbed position.

Back

pure tone

Front

a sound containing a single frequency

Back

destructive interference

Front

The result of the superposition of two waves which meet exactly out of phase, crest to trough and trough to crest

Back

rarefaction

Front

a region of slightly reduced air pressure immediately following a condensation

Back

Threshold of hearing

Front

The smallest sound intensity that the human ear can detect (1x10^-12 W/m^2 or 0 dB)

Back

beats

Front

A periodic variation in the amplitude of a wave resulting from the linear superposition of waves that have slightly different frequencies

Back

Intensity level

Front

A quantity which relates the intensity of a sound to some reference intensity level (dB)

Back

wave

Front

A traveling disturbance which carries energy

Back

condensation

Front

a region of slightly reduced air pressure produced by a vibrating source

Back

wavelength

Front

The distance along the length of a wave between two equivalent points.

Back

transverse wave

Front

The wave disturbance is in a direction perpendicular to the direction of wave travel.

Back

standing wave

Front

The pattern of disturbance that results when oppositely traveling waves of the same frequency and amplitude pass through each other.

Back

period

Front

The time required for a wave to travel one wavelength.

Back

pitch

Front

A subjective quality related to the frequency of sound detected by the human ear. High pitch is high frequency and low pitch is low frequency.

Back

doppler effect

Front

A change in the frequency of sound detected by an observer because the sound source and the observer have different velocities with respect to the medium.

Back

frequency and amplitude

Front

What does not change the speed of a wave?

Back

constructive interference

Front

The result of the superposition of two waves which meet exactly in phase, crest to crest and trough to trough

Back

frequency

Front

The number of wavelengths per second which pass a given point

Back

longitudinal wave

Front

The wave disturbance is parallel to the line of wave travel.
