If a wave has a frequency of 10 Hz, then the time period of the wave will be
Correct answer: A. 0.1 s.
- A. 0.1 s.
- B. 1 s.
- C. 10 s.
- D. 100 s.
Explanation
The time period of a wave is the reciprocal of its frequency. Thus, the time period T = 1/frequency. Given that the frequency is 10 Hz, the time period T = 1/10 Hz = 0.1 seconds. Therefore, the correct answer is 0.1 s. The other options are incorrect because they are based on incorrect calculations of the reciprocal of the given frequency.

About Progressive Waves
Progressive waves transfer energy through a medium or space while particles oscillate about their equilibrium positions. The work includes amplitude, wavelength, frequency, period, phase difference, wave speed and the progressive wave equation, while distinguishing travelling waves from stationary waves, where the pattern has fixed nodes and antinodes.
