Answer 2

The correct answer is option 1) hertz.

• The shrillness of the sound is known as the pitch of the sound. The pitch is high or low depending on the frequency of sound waves produced by the vibrating body.  

• The unit of measuring the pitch of a sound is hertz. One vibration made by the vibrating body per second equals the value of one hertz.
