Answer 2

Frequency

Explanation:

Frequency is the number of times a cycle is completed in one second. Frequency is inversely proportional to time period. Time period is the time taken to complete one cycle of the wave. The hertz is the derived unit of frequency in the International System of Units (SI Units). The symbol of Hertz is Hz. It is named after Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves. Humans are capable of hearing sound waves of frequency between 20 Hz and 20,000 Hz only.
