This is the back and forth motion around an equilibrium point.
What is vibration?
100
This type of interference increases the amplitude of a wave.
What is constructive interference?

If a wave vibrates back and forth 5 times each second and its wavelength is 2 meters, what is its speed?
Equation: wavespeed = wavelength x frequency
What is 10 m/s?
100
A change in this results in a change of pitch of a noise.

The picture representation of a wave is this type of curve.
What is a sine curve?
200
A slower moving object produces this type of a V-shape bow wave.
What is broader or wider?
200
A wave moves with a speed of 4 m/s. the crests are 32 m apart. What is the period?
Hint: You have to work backwards with the equation.
Equation: wavespeed = wavelength x frequency
What is 8 seconds?
200
As a wave source approaches an observer, the frequency of the waves does this.
What is increases?
200
This food has negative calories. It actually takes more calories to eat it than it puts into your body.
What is celery?
300
When the motion of a wave is back and forth compressed along the same line, it is this type of wave.
What is a longitudinal wave?
300
This type of interference decreases the amplitude of a wave.
What is destructive interference?
300
A man notices that 10 waves pass by him in 30 seconds. He also notices that their crests are 5 meters apart. What is the wavelength of the waves?
What is 5 meters?
300
When dealing with the Doppler effect, the increased frequency of the waves results in this being decreased.
What is wavelength?
300
Rob Thomas sings for this group.
"But I'm not crazy, I'm just a little unwell
I know right now you can't tell
But stay awhile and maybe then you'll see
A different side of me"
Who is Matchbox 20?
400
Frequency is measured in this type of units.
What is hertz?
400
A faster moving object produces this type of a V-shape of a bow wave.
What is narrower?
400
An object completes 10 vibrations in 12 seconds. What is the frequency?
What is 0.833 Hz?
400
As a wave source moves away from the observer, the frequency of the waves does this.
What is decreases?
400
In The Great Gatsby, this phrase is said 55 times.
What is "old sport"?
500
Sound waves are an example of this type of wave.
What is longitudinal wave?

The time of a full vibration is called this.
What is period?
500
If you double the frequency of a vibrating object, this will happen to the period.
What is reduced by half?
