UNILAB Amplified Microphone
UNILAB Amplified Microphone
E8R09545
Product code: E8R09545
Product Description
The amplified microphone is a great way to observe sound waves on an oscilloscope. The output level is much higher than the traditional crystal microphones giving a very clear trace. Two amplified microphones can be used with a storage oscilloscope or Motion QED to measure the speed of sound.
Specification:
- Battery: 3 x AAA (not supplied)
- Gain: 125
- Frequency range: 0 - 20kHz
- Output :± 2V a.c.
- Key Stage 3 Physics - Waves: Sound needs a medium to travel, the speed of sound in air, in water, in solids. Pressure waves transferring energy; use for cleaning and physiotherapy by ultrasound; waves transferring information for conversion to electrical signals by microphone. Sound produced by vibrations of objects, in loudspeakers, detected by their effects on microphone diaphragm and the ear drum; sound waves are longitudinal
- Key Stage 4 Physics - Forces and Motion: Speed of sound, estimating speeds and accelerations in everyday contexts.
- Key Stage 4 Physics - Waves: Amplitude, wavelength, frequency, relating velocity to frequency and wavelength.
- Use with an oscilloscope to visualise sound waves.
