Properties of Sound Waves
What kind of wave is sound wave?
Longitudinal Wave
It is a reflected sound wave and its strength depends on the reflecting surface.
Echo
What do you call the science of sound
Acoustic
Sound waves are mechanical waves, so they must always travel through
Matter
The bouncing back of a sound when it hits a barrier is called
Reflection
It is a region in a longitudinal wave where the particles are furthest apart
Rarefaction
Connected to the mouth to equalize pressure in its air-filled cavity. Contains three tiny bones that sound waves travel across.
Middle Ear
Through which medium does sound travel the fastest?
Solid
People use this type of echolocation to locate objects underwater.
Sonar
The region in a longitudinal wave where the particles are closest together.
Compression
What was the name (First name and last name) of your old science teacher.
Julio Fajardo
frequency is measured by this
Hertz
Waves combine to form bigger waves. It causes loud sounds, such as sonic booms.
Constructive Waves
Jet planes moving faster than the speed of sound can produce a very loud sound called a
Sonic Boom
True or False
Resonance is important for making music.
True
Some properties of the sound are:
Frequency, Amplitude and Pitch
Happens when two or more sound waves overlap and combine to form one wave.
Interference
List the two main factors that affect the speed of sound are
Temperature and the medium
Some animals—such as dolphins, bats, and beluga whales—use echoes to hunt for food and find objects in their path. This is called
echolocation.
