Q: What is the approximate range of sound for humans?
  • A. 20Hertz to 2000 Hertz
  • B. 20Hertz to 200Hertz
  • C. 20 Hertz to 20000 Hertz
  • D. 2 Hertz to 2000 Hertz
Correct Answer: Option C - Sound waves are a type of longitudinal waves that originate from vibrations in objects whose sound waves have a frequency less than 20 Hertz are called infrasonic sound waves while waves with a frequency between 20Hertz to 20,000Hertz are audible waves frequency for human. High frequency sound waves are called ultrasonic waves.
