High Pitch,- Closer together,
Farther apart- Low Pitch
True or false: there are certain sound frequencies/pitches that humans are unable to hear.
TRUE
The distance between the resting point and the trough of a wave (or the resting point and the crest).
What is Amplitude?
Build and label a Wave
Crest , Trough, Resting Point
In the tuning fork and water experiment, what happened after the tuning fork was hit on a table and placed in the water? What caused this?
The sound vibrations caused by hitting the tuning fork on the table made the water vibrate and at times splash out of the jar.
What would the following sound waves look like? A&F
A Yelling Lady, and Whispering Man
A Yelling Lady- High Amplitude/High Frequency, A whispering Man-Low Amplitude/Low Frequency
True or False: Sound waves CANNOT be reflected, refracted, or absorbed like light waves can.
FALSE
What is Wavelength?
The distance between one crest or trough to the next.
Draw a sound wave that would have a low volume and high pitch
Low Crest, Closer together
An explosion happens in the distance. One person is only looking for the explosion, one person is only listening for the explosion, and one person is feeling for the explosion through the ground. List the order that the explosion will reach the people: through seeing, listening, or feeling?
First: The person looking for the explosion
Second: The person feeling for the explosion through the ground
Third: The person listening for the explosion

Fastest, Liquid, Gas, Medium, Solid, Fastest
Gas, Liquid, Solid, Fastest, Slowest, Medium
