Sound Waves Flashcards
Frequency
The amount of wave cycles. Calculated in hertz (Hz)
Medium
The material to which a wave travels (solid, liquid, or gas).
Pitch
How high or low a tone is
Volume
How loud a sound is
What is a trick to finding frequency?
Count the crests
When can you not use the frequency trick?
When the wave doesn’t start on the line of origin
Volume corresponds with ______.
amplitude
The higher the amplitude the _____ the sound.
louder
The _____ the amplitude the softer the sound.
lower
What does pitch correspond with?
Frequency/Wavelength
The _____ the frequency the higher the pitch.
higher
The lower the frequency the ______ the pitch.
lower
The higher the frequency the ______ the wavelength.
smaller
The lower the frequency the ______ the wavelength
longer
Vacuum
A place with no air
Wave
A disturbance that transfers energy from one place to another without transferring matter
Amplitude
Hieght of a wave. Measured from the line of origin to the crest or line of origin to the trough
Wavelength
The disturbance between two identical points on a wave
Crest
Highest point on a wave
Trough
Lowest point on a wave
Line of Origin
Line where the wave sits
