What is the frequency of the body when its time period is 2 seconds?
Correct answer: D. 0.5 Hz
- A. 1 Hz
- B. 2 Hz
- C. 0.2 Hz
- D. 0.5 Hz
Explanation
The frequency of a body in Simple Harmonic Motion (S.H.M) is the number of complete oscillations it makes per second. The frequency (f) is the reciprocal of the time period (T), which means: Frequency (f) = 1 / Time period (T) Given that the time period is 2 seconds, we can calculate the frequency using the above formula. Frequency (f) = 1 / 2 seconds = 0.5 Hz

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
