100
Which wave has a higher frequency?
Wave 4
100
In sound waves, the amplitude of the wave determines this characteristic of the sound.
What is loudness (or volume)
100
What is #4?
Crest

Who is Ms. Condon's future husband?
Justin Bieber, with all due respect to Hailey
200
Define: Frequency
Number of waves that pass a point in a second
200
What is the word we use to describe how high or low a sound is?
Pitch
200
True or False: A wave with larger amplitude carries more energy than a wave with a smaller amplitude
What is True
200
What is #3?
Amplitude
200
Where is Ms. Nepo, Ms. Barkstrom, and Mrs. Duggan from?
Chicago
300
Define: Amplitude
Distance between the middle (equilibrium) and crest or trough of a wave
300
What is the unit used to measure the frequency of a wave
Hz (Hertz)
300
A sound wave with a very small amplitude would be described as sounding as this
What is quiet
300
What is #2?
Trough
300
As a group, stand up and sing Baby by Justin Bieber for 300 points
Oh-ooh-whoa-oh-oh-oh-oh
Oh-ooh-whoa-oh-oh-oh-oh

400
What is the name of the small electronic device that provides a sense of sound to people? One part goes on the outside of the ear, one part goes on the inside.
Cochlear Implant
400
As frequency increases, what happens to the wavelength?
The wavelength decrease (Inverse Relationship)
400
What unit do we typically measure amplitude with?
meters
400
What is #1?
Wavelength
400
Who are our four assistant principals?
Mr. Mac, Mr. Smith, Mrs. Jackson, Mrs. Williams
500
Define: Rarefaction
A part of a mechanical sound wave where the particles are furthest apart.
500
As frequency decreases, what happens to the amplitude?
Nothing. Frequency and Amplitude are independent of each other. There is no connection!
500
How can you find the amplitude of a wave?
Measure the height from the middle of the wave to the top (crest) or the bottom (trough)
Bonus Points: The difference in pressure between rarefaction and compression points
500
What do you call the part of this wave where particles are very close together?
Compression
