Parts of a wave
this is the top of a wave
crest
when a sound wave bounces off of an object and comes back you hear a(n) ________________
echo
wave speed vs frequency would produce a _________________ graph
linear
When two waves are in phase and pass through each other, they undergo _____________________________.
constructive interference
What is the frequency of a wave that undergoes 7000 vibrations in 15 s?
467s
this is the bottom of a wave
trough
in the doppler effect, as a sound sources approaches the perceived frequency....
increases
wavelength vs frequency would produce a _______________ graph
inverse
When two waves are ________ __ ____________ and pass through each other, they will undergo destructive interference.
what is the period of a wave that undergoes 17 cycles in 51s?
this is the distance from one part of a wave the the next corresponding part on a wave
wavelength
sound waves are _______________ waves, meaning they cannot travel in a vacuum
mechanical
period vs frequency would produce a ______________________ graph
inverse
a _____________ is a periodic fluctuation in loudness when two sounds of similar frequency interact with each other.
beat
What is the wavelength of a wave that undergoes 4000 cycles in 20s and travels 5000 m/s?
25 m
this is the distance from the equilibrium position to the crest or the equilibrium position to the trough
amplitude
sound waves are __________________ waves, meaning they're amplitudes are parallel to their motion
longitudinal
a student graphs wave speed vs frequency. What does the slope represent?
wavelength
When the frequency of a vibration forced on an object matches the object's natural frequency. This causes a dramatic increase in amplitude.
resonance
What is the period of a wave that travels 300 m/s with a wavelength of 0.08 m?
.00027 s
this is the time it takes for 1 vibration or wave cycle to occur
period (I bet the last group said frequency)
sound waves have areas of high and low pressure called _________________ and __________________
compressions and rarefactions
a student graphs wavelength vs wave speed. What does the slope represent?
period
occurs when an object is made to vibrate by another vibrating object nearby.
forced vibration
297 m
