Characteristics of Sound
A small pebble dropped in a puddle will create what type of disturbance?
What is a small wave?
The most common unit used to measure loudness.
What is decibel?
This is created when sound waves bounce off or reflect off a solid object.
What is an echo?
When you drop a pebble in a pond, it makes waves in this shape.
What is a circle?
Whales and tubas make make slow vibrations and low frequency that have this sound.
What is low pitch?
The distance between the crest of one wave to the crest of the next.
What is wavelength?
Waves with a high amplitude have more or less energy
What is more energy (loudness)?
What type of medium is water?
What is a liquid?
The extent to which a sound can be heard.
What is a loudness?
Waves with a high frequency have more or less energy.
What is more (high pitch)?
This is what waves do when they reach shallow areas.
What is break? not on test
A sound that consists of a random mix of frequencies.
What is noise?
The particles in longitudinal waves (sound waves) move like this.
What is back and forth or parallel?
Waves with short wavelength have more or less energy.
What is more energy or high pitch?
The speed at which a wave travels through a medium..
What is wave speed?
Earthquakes cause these huge waves, often called tidal waves.
What are tsunamis? not on test
