Sound Waves Flashcards
1
Q
What is amplitude?
A
The amplitude is the maximum displacement of a wave from from its equilibrium (middle) position.
When representing sound, this is how loud the sound is.
2
Q
What is wavelength?
A
Wave Distance is the space from one wave to the next, measured in Metres (m)
3
Q
What is frequency?
A
The number of waves passing a point per second, Measured in Hertz (Hz).
4
Q
What is Time period?
A
Time it takes for 1 wave to pass a point. Measured in seconds (s)
5
Q
What is Compression?
A
In a longitudinal wave, the point where the wave fronts/particles move close together.
6
Q
What is Rarefraction?
A
In a longitudinal wave, the point where the wave fronts/particles spread out.
7
Q
Wave Speed Equation?
A
Speed = Wavelength x Frequency
S
F W
