Disturbances that transfer energy without carrying matter.
100
What is a crest?
the highest part of a transverse wave
100
What is a reflection and how can it be used to tell the depth of a lake
The bouncing back of a wave when it hits a surface through which it cannot pass. The longer it takes to bounce back, the further away the object is.
100
A wave's ___________ affects the loudness of a sound wave.
amplitude
100
What happens to wave length a wave frequency increases?
What is, gets shorter.
200
What are mechanical waves?
The type of waves that needs a medium to transfer energy.
200
What is a wavelength?
the distance between crest to crest or trough to trough in a transverse wave or from compression to compression or rarefaction to rarefaction in a compressional wave.
200
At what speed do electromagnetic waves travel? The speed of ___________.
The speed of light.
200
Where can sound NOT travel? (Technical science term)
A vacuum
200
Particles move parallel to the flow of energy?
What is a compressional / longitudinal wave.
300
What is a rarefaction?
The parts where the coils or particles are spread out in a longitudinal or compressional wave
300
What is frequency?
the number of complete waves that pass a given point in a certain amount of time
300
What has a higher frequency radio waves or gamma waves.
Gamma waves
300
What type of wave does sound travel as?
What is a compressional / longitudinal wave?
300
In what type of waves are the particles vibrated perpendicular to the flow of energy?
What is a transverse wave.
400
What is a medium?
The material through which a wave travels.
400
What is Hertz?
the unit of measurement for frequency
400
What is a seismic wave and where does it start?
A seismic wave is caused by an earthquake and starts deep underground.
