Question
The time period of the sound wave whose frequency is 0.5 Hz is ____s.
- 1
- 2
- 3
- 4
Hint:
The time period of the sound wave whose frequency is 0.5 Hz is 2 s.
The correct answer is: 2
-
- The time period of a sound wave is the time consumed to complete vibration in a density of a medium.
- The frequency will be equal to two cycles per second.
- Time can be derived as 1/f, that is cycles per second.
- f = 0.5 Hz
- Therefore, time period = 1/0.5 = 2 s.
