ensor" that emits sound waves to measure distance from the sensor, why does the range of the sensor varying with frequency of the emitted sound waves?...
Using a "pasco motion sensor" that emits sound waves to measure distance from the sensor, why does the range of the sensor varying with frequency of the emitted sound waves?
Sensing FrequencySensing frequency is inversely proportional to sensing distance (Range).For eg. A 50 kHz sound wave may work to 10 m or more, a 200 kHz sound wave is limited tosensing ranges of...
