|
waves
|
rhythmic disturbances that carry energy through matter or space.
|
|
|
medium
|
a material through which a wave transfers energy.
|
|
|
transverse wave
|
the medium moves at right angles to the direction the wave travels.
|
|
|
crests
|
the highest point of a wave.
|
|
|
troughs
|
the lowest points of a wave.
|
|
|
wavelength
|
the distance between a point on one wave and the identical point on the next wave, such as from crest to crest or trough to trough.
|
|
|
amplitude
|
the distance from crest(or trough) of a wave to the rest position of the medium.
|
|
|
frequency
|
the number of wave crests that pass one place each second.
|
|
|
compressional wave
|
matter that vibrates in the same direction as the wave travels.
|
|
|
pitch
|
the highness or lowness of a sound.
|
|
|
intensity
|
depends on the amount of energy in each wave.
|
|
|
loudness
|
the human perception of sound intensity.
|
|
|
ultrasonic technologyt
|
technologytechnology using high frequency waves for many different purposes.
|
|
|
music
|
created using specific pitches and sound quality.
|
|
|
resonance
|
if the sound that reaches an object is at the same frequency as the natural frequency of the object, the object will begin to vibrate.
|
|
|
quality
|
describes the differences among sounds of the same pitch and loudness.
|
|
|
interference
|
the ability of two or more waves to combine and form a new wave.
|
|
|
reverberation
|
the effect produced by many reflections of sound.
|
|
|
noise
|
sound that has no set pattern or definite pitch.
|
|
|
acoustics
|
the study of sound
