VERNIER MICROPHONE
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

Requirements:
This sensor requires suitable software and an interface such as one of the Vernier LabQuest variations.
For comprehensive details of the possible sensor/interface/software combinations see the Compatibility Guide link below.

Specifications:
• 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.

Educational use only:
Vernier and Kidwind products are designed for educational use. They are not appropriate for industrial, medical or commercial applications. Details

• Warranty: 5 year limited warranty
