The product of frequency and time period is equal to:
Correct answer: D. 1
- A. 2
- B. 3
- C. 0
- D. 1
Explanation
The product of frequency and time is equal to 1 according to the formula f=1/T where f represents the frequency having the units, seconds-1, and T represents the Time period having the units, seconds.

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.
