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
What looses energy to the medium quicker, high or low frequency?
What is high frequency
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 light.
200
What is a decibel?
unit for measuring loudness
200
Particles move parallel to the flow of energy?
What is a 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 longitudinal wave?
300
Explain how density of a material can affect the speed of a wave?
What is, objects that have a greater density have particles that are packed tightly and that makes is harder for them to vibrate.
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.
400
What is an echo?
a reflective sound wave
400
In what type of waves are the particles vibrated perpendicular to the flow of enrgy?
What is a transverse wave.
500
Name 4 types of electromagnetic waves?
Possible answers:
Radio waves Infrared waves
Visible light waves Ultra violet waves
X-Rays Gamma Rays
500
What is Amplitude?
How far a particle of a medium is moved from its resting point.
500
Generally speaking, mechanical waves move quickest through which medium?
