How Sound Moves
Every sound starts with this fast, back-and-forth motion.
What is Vibration
A bird chirping has a high version of this, while a deep drum has a low version
what is pitch?
This part of the ear is shaped like a snail shell and sends signals to the brain
What is the cochlea
This is the general term for any solid, liquid, or gas that sound travels through
What is a medium?
Sound is a form of this, just like light or heat.
What is energy?
This is the part of a sound wave where the molecules are squished tightly together.
What is compression
This is the measurement of how many vibrations happen in one second.
What is frequency?
This thin skin vibrates as soon as a sound wave hits it.
What is the eardrum?
Sound travels fastest through this state of matter because the atoms are packed tight
What is a solid?
Whale songs travel through this liquid medium
What is water?
Because sound waves move by squishing and stretching, they are called this type of wave
What is longitudinal wave?
If a sound wave is very tall and has a lot of energy, it will have a high version of this.
What is amplitude?
This organ is responsible for telling you what a sound actually is (like music or a voice).
What is the brain?
Sound cannot travel here because there are no molecules to vibrate
What is the outer space/a vacuum?
If you increase the amplitude of a sound wave, you are making it ________
What is louder?
This is the part of a sound wave where molecules are spread far apart.
What is rarefaction?
A slow vibration results in this kind of pitch.
What is low pitch?
Name the three main "sections" sound passes through in the ear.
What are the outer, middle and inner ear?
Rank the three mediums (solid, liquid, gas) from slowest to fastest for sound travel
What is Gas, Liquid, Solid?
This is what happens to a sound the moment a vibration stops.
What is the sound stops?
