These are areas of high and low pressure in longitudinal (pressure) waves.
What compressions and rarefactions?
100
This is the speed of sound, in air, at sea level.

100
A standing wave on a string with three nodes is in this harmonic.
What is the second harmonic?
200
When a spring is stretched, this brings it back to equilibrium.
What is restoring force?
200
This is how your brain interprets different amplitudes in sound waves.
What is loudness?
200
A transverse wave, traveling at a velocity of 10m/s with a frequency of 30Hz has this wavelength.
What is .33m? Or what is 33cm?
200
Your brain interprets different sound frequencies as this.
What is pitch?
200
In a standing wave, this is the stationary part.
What is the node?
300
This is the only factor that influences the period of a pendulum.
What is the length of the arm?
300
These men were president of the United States of America and the Confederate States of America during the Civil War.
Who are Abraham Lincoln and Jefferson Davis?
300
This is the amplitude of a wave described by: y=3sin(2(pi)+4x)
What is 3?
300
An approaching ambulance sounds like it has a higher pitch than it actually does because of this.
What is the Doppler Effect?
300
These are two types of wave interference.
What are constructive and destructive?
400
This describes the distance that an oscillating object travels from equilibrium.
What is amplitude?
400
Penguins are these.
What are birds?
400
All mechanical waves travel through this.
What is a medium?
400
Stars moving away from us appear to have light that is more this than actual.
What is red?
400
This is the capital of New Hampshire.
What is Concord?
500
In a swinging pendulum, the velocity of the pendulum is this when the acceleration is at its maximum.
What is zero?
500
These go great with toast.
What are beans?
500
This describes the forward motion of a mechanical wave.
What is propogation?
500
These are the increasing and decreasing intensities of the sound produced by two interfering waves with different frequencies.
What are beats?
500
If a standing pressure wave in a closed tube is producing a first harmonic sound, then the wavelength is this compared to the length of the tube.
What is four times as long?
