Detailed Solution

 The above statement is  False.
The unit of frequency is called Hertz (Hz). The range of frequencies people and other animals can hear is called the hearing range. The human ear can perceive between 20 and 20000 (Hz) sounds. We cannot hear frequencies outside of this range because of how our ears function. As the pendulum's vibrations occur at a frequency below the human hearing threshold, no one can hear them. On the other hand, we can hear honey bees because their sound frequency is within our hearing range. The unit of length or distance is expressed in metres (m).
The correct statement would be that the frequency is measured in Hertz (Hz).
