Interacting in Harmony
this and that
100
It can't fix a car, but this does requires a medium through which to travel.
What is a mechanical wave?
100
Two Parter:
What is the name of the highest part of a wave? Not the toothpaste!
What is the name of the lowest part of a wave?
Crest and Trough
100
The maximum distance the particles of a medium move away from their rest positions as a wave passes through the medium. The larger this is in a mechanical wave, the larger the energy.
What is amplitude?
100
True or False: Increasing the frequency of a wave increases the speed of the wave
False: Increasing the frequency decreases the wavelength. The speed of the wave is dependent on the properties of the medium.
100
Two instruments sound different even though they play the same note. This is known as ____.
Timbre
200
A wave that moves the medium in a direction perpendicular to the direction in which the wave travels.
What is a transverse wave?
200
A sound wave has a wavelength of 0.5 meters. What is the frequency of the wave?
686 Hz
200
The distance between two corresponding parts of a wave.
What is wavelength?
200
True or False:
A high pitch wave has a large wavelength
False - It has a large frequency, therefore a small wavelength
200
Which type of air column can only produce odd number harmonics?
Close ended air columns
300
A wave that moves the medium in a direction parallel to the direction in which the wave travels.
What is a longitudinal wave?
300
The part of a longitudinal wave where the particles of the medium are close together.
What is a compression?
300
Frequency of a wave is doubled. What happens to the wavelength AND the speed of the wave?
Wavelength halves and speed remains the same (only medium changes the speed of the wave)
300
When two waves are in phase and the overall amplitude increases.
What is Constructive Interference
300
What harmonic and overtone is shown.
2nd harmonic
1st overtone
400
A wave that appears to stand in one place, even though it is really two waves interfering as they pass through each other.
What is a standing wave?
400
The part of a longitudinal wave where the particles of the medium are far apart.
What is a rarefaction?
400
Unit of measurement for frequency.
What is a hertz (Hz)?
400
Two sound waves are played at the same time, one at 400 Hz and the second at 402 Hz. What will happen?
A) the sound will be constantly louder
B) the sound will be a higher pitch
C) The sound will alternate between loud and quiet
C) This phenomena is known as Beats.

TWO PART QUESTION:
What string OVERTONE has 6 nodes?
How many times higher is the frequency than the fundamental frequency?
4th overtone (5th harmonic)
5x higher frequency
500
Sound wave is this type of wave
What is Longitudinal
500
A point of maximum amplitude on a standing wave.
What is an antinode?
500
The frequency of 300 waves that pass a point in one minute?
What is 5 Hz?
500
The increase in the amplitude of a vibration that occurs when external vibrations match an object’s natural frequency.
What is resonance?
500
Which harmonic and overtone is shown.
5th harmonic
2nd overtone
