We're going to look a bit more into this idea of the relationship between how long each vibration takes (period) and the number of vibrations per second (Frequency)
Start Wednesday by drawing a waveform with four antinodes, and label at least one wavelength and amplitude.
Remember, DO NOT HIT THE TUNING FORKS ON A HARD SURFACE!!! (just a gentle tap on something soft like your rubber shoe sole)
In Logger Pro, hook up the microphone to CH1, OPEN, PHYSICS WITH VERNIER, 35MATHEMATICSofMUSIC, and capture a screenshot of the sound from a tuning fork. Use the graph to determine the period of the wave (or do 10 and divide?), and then figure out how many of these wavelengths go by during each second. How does that compare to the number stamped on the tuning fork? Want more help getting connected? Click HERE
Look around at some other tuning forks, what do you notice about the ones with a higher frequency?
Just about everything has a natural resonant frequency, here's what might happen if you forget about that when building a bridge...
This resonance phenomena also applies to how we hear
And just in case you were wondering why we were getting dizzy in the previous unit(s), here's an explanation of how balancing works (and how momentum can cause dizziness!)
