Basics of Waves
100
What sound is measured in
What is decibels?
100
The number of wavelengths in a sound wave
What is frequency?
100
Used by humans to perceive sound
What are ears?
100
This is determined by the amplitude of the sound wave
What is loudness?
100

Waves cause materials to

what is vibrate?

200
Sound requires this to travel
What is a medium?
200
Determined by the frequency of the wave
What is pitch?
200
The outer, middle, and inner ear
What are the three basic parts of the ear?
200

There's no molecules here

what is outer space?

200

This type of wave travels in a back and forth motion

What is longitudinal waves?

300

Sound travels best in this type of matter

What is a solid?

300

Caused by the compression and rarefaction of atoms

What is the travel of sound waves?

300
Acts as a funnel to concentrate the sound waves toward your middle and inner ear. Contains the ear flap and the ear canal.
What is the Outer Ear
300
The more stable this is, the better a sound wave can travel
What is a medium?
300

Waves do not carry this, but they do carry energy.

What is matter?

400

Larger frequency equals

What is higher pitch?

400
The distance a wave oscillates from its resting position
What is amplitude?
400
Made up of a cochlea, semicircular canals, and the auditory nerve.
What is the Inner Ear?
400

How well a sound can be heard

What is loudness?

400

Another word for echo

What is reflect?

500

Created when objects vibrate and travels through the compression and rarefaction of atoms

What are sound waves?

500
The shift in frequency of acoustic or electromagnetic radiation emitted by a source moving relative to an observer as perceived by the observer: the shift is to higher frequencies when the source approaches and to lower frequencies when it recedes.
What is the Doppler Effect?
500

Contains three tiny bones that sound waves travel across.

What is the Middle Ear?

500
Differing frequencies can cause a sound wave to be more "direct" or "broad"
What is pitch?
500

This is the vibration produced in one object that is caused by the vibration produced by another

What is resonance?
