Sound
Waves with bigger amplitude transfer (more/less) energy than waves with less amplitude.
More
When an object makes sound, __________ is applied to a part of an object.
force
The ____________ between compression bands appears to change when we change the frequency of vibration.
distance
Motion graphs with softer sounds have a __________ amplitude.
lower
The density of particle ____________ gets greater when the amplitude of vibration at the sound source increases.
*HINT: Think about the particle simulation video
compression
Sound is created through _______________.
vibrations
Motion graphs of __________ sounds have higher amplitude.
louder
The distance from "at rest" to the peak or trough is called _________.
amplitude
How would we describe a "tall" sound wave in terms of amplitude?
high amplitude wave
Different _________ sounds are produced from differences in the way the sound source vibrates (as in slower/faster).
pitch
Sound transfers energy through ______________ between particles in a medium.
collisions
When an obejct makes a sound, a force is applied to part of an object, the object ________, and changed shape.
deforms
Collisions between particles in the medium result in these compression bands moving _____________ from the sound source.
away
When an obejct makes a sound, force is applied, the obejct deforms, and ________ is transfered to the object.
energy
How would we describe a "short" sound wave in terms of amplitude?
low amplitude wave
Sound stops when the _______________ stops.
vibration
When a greater force is appled, objects vibrate more, creating a _________ sound.
louder
Sound can travel through ____________, ___________, and ___________.
solids, liquids, and gases
Sound needs ____________, such as a solid, liquid, or gas, to travel.
*Hint: solid, liquid, and gas are all states of this
matter
A low frequency sound wave has few peaks and troughs.
True or False
True
All solid object ________ when making sounds.
vibrate
As the pitch changes, the ____________ of the vibration of the object changes.
frequency
A high frequency sound wave has very few peaks and troughs.
True or False
False
How could we describe a tall sound wave with many peaks and troughs.
*in terms of both frequency and amplitude
high amplitude and high frequecy
How could we describe a short sound wave with few peaks and troughs?
*in terms of amplitude and frequency
low amplitude, low frequency
