The number of vibrations per second is called:
Correct answer: C. Frequency
- A. Amplitude
- B. Wavelength
- C. Frequency
- D. Velocity
Explanation
Frequency (f) is the number of complete oscillations per second, measured in Hertz (Hz). f = 1/T.

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.
