Flashcards in Chapter 13: Vocab Deck (37)
Moves through matter. (Cannot travel through a vacuum)
Vibrations that can pass through electric and magnetic fields.
High point of a wave.
Low point of a wave.
The distance from the midpoint to the top of the crest. (Or bottom of the trough)
From one crest to the next.
Number of vibrations passing a given point per unit of time.
Unit of frequency, one vibration per second.
The time required for one complete vibration.
The speed which waves travel.
A wave in which the particles move perpendicular to wave motion. (Water waves)
Particles move back and forth in the direction of wave motion. (Aka compressional waves)
A thinning out. (Slinky/sound waves)
How high or low a sound is. (Dependent upon the frequency of the vibrating object.)
Detects human sounds 20-20,000 hz.
Frequency less than 20 hz.
Frequency greater than 20,000 hz.
Reflection of sound.
Bending of sound
The vibration of a sample of matter due to interaction with a frequency that is the same as the sample's natural frequency.
A frequency at which an electric object tends to vibrate.
The combining of two or more waves of the same wavelength.
The crest of one wave overlaps the crest of another higher amplitude.
The periodic variation loudness due to interference of two waves of slightly different frequency.
One wave crest overlaps the trough of another lower amplitude.
A stationary wave pattern formed when 2 sets of identical waves pass through a medium in opposite direction.
The part of a standing wave that doesn't seem to move.
The part of a standing wave that moves the most.
