Sound Intro
A quick back and forth movement.
What is a vibration?
Length of a single wave cycle. Measured by the distance between 2 identical points on consecutive waves.
What is a wavelength?
A sound wave can not travel through outer space because of the lack of this.
What is a matter?
Amplitude and frequency do not effect each other (True or False)
True
How high or low a sound is.
What is pitch?
Hight of the wave. The distance between the equilibrium line (resting point) and the crest.
What is amplitude?
The bouncing back of a sound wave off of a barrier creates this.
What is an echo?
Amplitude and frequency: cheer team
high amplitude (loud)
high frequency (high pitched)
Three mediums sound can travel through.
What is gas, liquid, and solid?
The number of wave cycles that pass a given point in a certain amount of time.
What is frequency?
High frequency waves result in this type of sound.
What are high pitched sounds?
Amplitude and frequency: heartbeat
low amplitude (quiet)
low frequency (low pitch)
Sound travels best through this medium.
What is solid medium?
When changing the amplitude of a sound, this changes.
What is volume/loudness?
Sound is measured by this unit.
What is a decibel?
Amplitude and frequency: thunder
high amplitude (loud)
low frequency (low pitch)
Waves transfer this.
What is energy?
The mathematical relationship between wavelength and frequency.
What is inverse? (when one goes up the other goes down)
The unit of measure for pitch.
What is hertz?
Frequency: the thin strings on a ukulele or guitar when plucked
high frequency
