Type of mechanical wave that needs a source of energy to produce it.
1 point Check
What are surface, longitudinal, and transvers waves?
1 point Back to Category Slide
This has to occur before refraction can take
place.
2 points Check
What is enter a new medium at an angle?
2 points Back to Category Slide
This causes an ambulance siren to seemingly change
frequencies as it passes you.
3 points Check
What is the Doppler Effect?
3 points Back to Category Slide
When two waves collide and the result is a
smaller wave than the originals.
4 points Check
What is destructive interference?
4 points Back to Category Slide
Frequency of sound you hear as a sound source
approaches you.
5 points Check
5 points Back to Category Slide
What is higher freq. than when the source is
stationary?
Speed of a wave with a wavelength of 15 m and
frequency of 4 Hz.
1 point Check
What is 60 m/s?
1 point Back to Category Slide
Formula for determining speed of a wave.
2 points Check
What is speed = frequency x wavelength?
2 points Back to Category Slide
Mechanical waves can move through this
medium.
3 points Check
What is solid, liquid, or gas?
3 points Back to Category Slide
Transverse and longitudinal waves both
do this.
4 points Check
What is transfer energy through a medium?
4 points Back to Category Slide
Part of ear that amplifies the vibrations from
sound waves.
5 points Check
What is middle ear?
5 points Back to Category Slide
A disturbance sends ripples across a tub of water. The ripples are
this type of wave.
1 point Check
What is a surface wave?
1 point Back to Category Slide
We measure here to here to find amplitude of
wave.
2 points Check
What is crest (or trough) to midpoint, or rest
position.
2 points Back to Category Slide
This wave causes the medium to vibrate in a direction parallel to the
wave’s motion.
3 points Check
3 points Back to Category Slide
What is a longitudinal wave?
Length of time it takes for one complete
wavelength to pass a fixed point.
4 points Check
4 points Back to Category Slide
What is a period?
Waves in a rope shook up and down are this type
of wave.
5 points Check
What is transverse?
5 points Back to Category Slide
If two waves collide to form a temporary larger wave, the interference
is this kind.
1 point Check
What is constructive?
1 point Back to Category Slide
In a transverse wave, this is measured crest to
crest or trough to trough.
2 points Check
What is wavelength?
2 points Back to Category Slide
Instead of crests or troughs, a longitudinal
wave has these.
3 points Check
What are compressions and rarefactions?
3 points Back to Category Slide
The wavelength of an earthquake wave if its
speed is 10 km/s and its frequency is 5 Hz.
4 points Check
What is 2 km?
4 points Back to Category Slide
If a wave with relatively large wavelength passes through a
relatively small hole, this will occur.
5 points Check
What is diffraction?
