A medium (phases of matter)
A. Higher sound waves equal
B. Lower sound waves equal
A. Louder sounds
B. Softer sounds.
How we hear sound. We use the words high or low to describe this.
Determined by the frequency
Pitch
What vibrate to produce sound
Instruments

Solid
How Frequency and pitch are measured
Hertz (HZ)
True or false: smaller objects, have a higher pitch while larger objects have a lower pitch
True
Sound travels in
Compression waves
Used to detect and locate objects, underwater, using sound waves
Sonar
Used by some animals to navigate and since their surroundings, using sound waves
Geolocation
