If an object executes 10 oscillations per second, then its frequency in kilohertz is equal to:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 0.01.
- Frequency in simple terms is the no. of repetitions. 1 Hertz = One cycle or oscillation per second.
- Frequency is the reciprocal of time (in seconds), hence the SI unit is s-1.
- Frequency = 10 Hz. 1 KHz = 1000 Hz.
- Frequency in KHz = 10/1000 = 0.01 KHz.
