Vocabularg
This is a back-and-forth movement.
What is vibration
This tells how loud or soft a sound is.
Volume
Sound is caused by this.
Vibrations
Will also take a mechanical movement that then interacts with matter
The formula for frequency is this
The number of waves over time
Wave/ time
This is the highest point of a wave
What is a crest
This tells how high or low a sound is.
Pitch
Sound travels fastest through this state of matter
Solids
If 10 waves pass in 2 seconds, what is the frequency
5Hz
These are areas where particles are pushed together in a longitudinal wave.
What are compressions?
A wave with greater amplitude has this
A greater volume
Solids, liquids, and gases are types of this
Matter
If 20 waves pass in 4 seconds, what is the frequency?
5Hz
This is the distance between two crests or two troughs.
What is wavelengths
wave with higher frequency has this
A greater pitch
Sound cannot travel through this
A vacuum
If 24 waves pass in 6 seconds, what is the frequency
4Hz
This occurs when sound energy is taken in by a material instead of bouncing back.
Absorption
If a wave has low amplitude and low frequency, describe its sound.
A quiet low pitched sound
This happens when sound waves bounce off a surface
It reflects/ reflection
If 81 waves pass in 3 seconds, what is the frequency
27 Hz
