Wave Relationship
A wave is a way __________ moves from one place to another without moving matter permanently.
energy
A wave hit a material and bounce back is called?
reflection
As an ambulance approaches, sound becomes what?
higher pitch/frequency
What are the motion of p-wave? (single term)
longitudinal or parallel
When an ambulance passes you, the siren changes pitch because of this effect.
Doppler Effect
The distance from the midpoint to the crest is called?
amplitude
Entering a new medium and slightly changing direction is called?
refraction?
As a source is moving toward you, the wavelength becomes what?
smaller
The area where certain seismic waves are not detected are called what?
shadow zones
Scientists study waves to learn about Earth’s interior using this machine.
Seismograph
What happens to wavelength if frequency decreases 4 times assuming wave speed is the same? (include the magnitude)
wavelength increases 4 times
Two crests combining is called?
constructive interference
340 to 343 mi/hr
The amount of shaking or damage caused by an earthquake is called?
intensity
Cell Phones communicate using this type of wave.
radio wave
What happens when a material enter a new medium?
The wave speed changes and it changes direction.
Light passing through hair and "splitting" is called?
diffraction
What part of the wave does not change due to the doppler effect?
wave speed
This feature of an earthquake is the same regardless of location or medium.
magnitude
This device uses sound waves to detect objects.
radar
What is the wavelength if the wavespeed is 4.0 cm/s and the frequency is 16 s-1? (include unit)
0.25 cm
Hearing sounds around a corner is a example of what?
diffraction
