Wave Basics
Waves transfer this from place to place.
energy
The height of a wave above its resting point.
amplitude
Water waves are this type of wave because they move up and down.
transverse waves
Sound waves cause these to vibrate in the air.
air particles
When energy increases, amplitude does this.
increases
Waves do not transfer this from place to place.
matter
The distance from the peak of one wave to the peak of the next wave.
wavelength
Sound travels as this type of wave.
longitudinal waves
These tiny pieces moved on top of the speaker when music was playing.
salt
When energy increases, wavelength does this.
decreases
Waves are regular patterns of this.
motion
The highest parts of a transverse wave.
peaks
Longitudinal waves have this repeating pattern.
compression and expansion
Sound cannot be heard in a vacuum jar because this is removed.
air
Adding energy to a transverse wave makes it become this.
taller
Waves show this kind of repeated design.
repeating pattern
The lowest parts of a transverse wave.
troughs
Zoe and Izzy used this object to demonstrate both transverse and longitudinal waves.
spring
Sound waves can move in this way.
in all directions
When wavelength gets shorter, the waves are this.
closer together
In water, this object in the video helped show that waves do not carry matter from place to place.
ball
The line or level from which amplitude is measured.
resting point
This motion describes transverse waves, not longitudinal waves.
up and down
Sound cannot travel without these.
air particles
This type of wave includes sound waves and has compressions and expansions.
longitudinal waves
