In the absence of damping force, when driving frequency is equal to the oscillating frequency then the amplitude of the oscillation will become:
Correct answer: C. Maximum
- A. Zero
- B. Minimum
- C. Maximum
- D. Infinity
Explanation
Please note that the correct option is c) Maximum. In the absence of damping force, when the driving frequency matches the natural oscillating frequency of the system, the amplitude of the oscillation becomes maximized due to resonance.

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.
