Question

Which of the following time periods of the sound wave would result in the highest pitch?

• A. 0.5 s
• B. 0.05 s
• C. 5 s
• D. 50 s

Answer 1

The correct option is B 0.05 s

Pitch depends on the frequency of the sound. Higher the frequency, higher the pitch.
As we know, frequency is inversely proportional to the time-period. The shorter the time-period, the higher the frequency.
0.05 s time-period is the least. Thus, frequency will be the highest.
Hence, the pitch will be highest in 0.05 s time period.
