Less than 20 Hz - Infrasonic range
20 Hz- 20000 Hz - Subsonic range
Higher than 20 kHz - Ultrasonic range
The correct option is C. 20 Hz- 20000 Hz - Subsonic range.
Less than 20 Hz= infrasonic range
20Hz-20000 Hz= Audible range
Higher than 20000 Hz= Ultrasonic range
Find the minimum and maximum wavelengths of sound in water that is in the audible range (20-20000 Hz) for an average human ear. Speed of sound in water =1450ms−1.
