Question
A vibrating body:

Answer

  1. Will produce sound which depends upon frequency
Explanation:
A vibrating body vibrates the surrounding air, and when these vibrations reach our ears we hear sound. But, some vibrations cannot be perceived as sound to humans as human ears can only detect sound in the frequency range of 20Hz to 20,000Hz, so depending upon the vibration frequency, can only we define a vibration as sound.
