A resonance occurs when driving frequency is:
Correct answer: C. Equal to the natural frequency
- A. Less than the natural frequency
- B. Greater than natural frequency
- C. Equal to the natural frequency
- D. Equal to zero
Explanation
Please note that the correct option for resonance is c) Equal to the natural frequency. When the driving frequency matches the natural frequency of the system, resonance occurs, leading to a strong response and increased amplitude of oscillation.

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.
