Vernier Microphone

Order code: MCA-BTA
Purchase QTY: (Each)1+    
Scientrific's price  $122.00    
Note: Prices do NOT include GST or freight

Use the Vernier microphone to display and study the waveforms of sounds from voices and musical instruments. It is also appropriate for speed of sound experiments.

Activities with sound waves:
Demonstrate how the wave pattern changes when frequency and amplitude are changed
Compare the waveforms from various musical instruments
Have students capture the waveform of the sound of a tuning fork and model the sine wave using a function
Measure the speed of sound by using reflected sound waves in a tube
Demonstrate beat patterns
Determine the period and then the frequency of a sound by measuring the time between peaks on the waveform
Display the fast Fourier transform (FFT) of a sound

Frequency range: approximately 100Hz to 15kHz
Power: 1.45mA @ 5VDC
Stored calibration:
     slope: 1
     intercept: 0 (arbitrary units)
Note: The maximum data-collection rate of the interface affects the maximum frequency you can effectively sample.
