The ability to make things move or change.
energy
A pattern of motion that travels away from a source.
Wave
The starting point of a sound or wave.
the source
To make a picture in your mind using information.
visualize
If a wave has a high amplitude and long wavelength what will it sound like?
loud volume
low pitch
This determines how loud a sound is. It is also the height of a wave.
Amplitude
The specific motion of sound waves (up/down or back/forth).
back and forth
The person or animal that receives a sound signal.
the listener
Scientists use these because sound is usually invisible.
models / simulations
Low amplitude and short wavelength
low volume
high pitch
The distance between wave peaks.
wavelength
Sound waves must travel through this (like air or water).
material / particles
What is it called when animals or people share information with each other?
communication
The type of wave model that uses a long metal coil.
spring toy/slinky
high amplitude and short wavelength
loud sound
high pitch
To share information.
communicate
True or False: Waves travel to the source
False
Sound is caused by ________
vibrations
This model showed us a bunch of people moving in one place but the energy traveling.
stadium wave
Low amplitude and long wavelength
Low volume
Low pitch
A repeating code. Something similar and repeated.
pattern
When a wave moves, the particles move only a ______.
little bit
A wave travels away from this place
the source
True or False: We cannot see air particles moving in a sound wave.
True
No amplitude and short wavelength
