Question
The time period of the sound wave whose frequency is 1 Hz is ____s.
- 1
- 2
- 3
- 4
Hint:
The time period of the sound wave whose frequency is 1 Hz is 1 s.
The correct answer is: 1
- The frequency and time period of a sound wave can be calculated in the same way.
- Frequency is equal to 1/time period whereas the time period is equal to 1/frequency.
- When the frequency is 1 Hz, the time period is 1/1 which is equal to 1 s.
