Frequency vs Amplitude

1.sound 1: 25
sound 2: 26
sound 3: 27
sound 4: 28
2. It got louder.
3. done

4.i) yes
ii) Amplitude increase, sound sensor value increase
5. If the amplitude is low, the sound sensor value is low. As amplitude increases, so does the value of the sound sensor. Therefore the amplitude affects the value of the sound sensor.
6. sound 1: 24
sound 2: 69
sound 3: 88
sound 4: 96
7. It got higher (but not louder) each time.
8. done

9. i) yes
ii) As frequency increases, the sound sensor value increases (though not with a steady value like with amplitude).
10. As frequency increases, the sound sensor value increases, but the sound sensor is not as sensitive to frequency as it is amplitude.
11. As wavelength or frequency increase, the sound sensor value will increase, though the sound sensor is not as sensitive to frequency as it is amplitude.
12. i) Yes, it would register when the amplitude got too high.
ii) No, because it is not very sensitive to frequency.
iii) No, It is not sensitive enough for something so prescience in frequencies.
iv) No it would not be able to distinguish between the amplitude of the cars and the frequency of the siren.
v) Yes it would simply wait for an increase in amplitude.
vi) Yes it would simply have to wait for an increase in amplitude.
13. You could do an experiment where you have a sound with a low frequency and you have to increase the amplitude on your own to see about how high the amplitude has to be to reach 50%. Then you could do the same for a sound with low amplitude and varying frequency. AKA Manipulate both amplitude and frequency.
14. volume, pitch
