The waveform of S.H.M. is________________?
Correct answer: B. Sine wave
- A. Standing wave
- B. Sine wave
- C. Square wave
- D. None
Explanation
In simple harmonic motion, displacement varies with time as a sine or cosine function, so its waveform is a sine wave. A standing wave may contain points that oscillate harmonically, but it is a pattern formed by interference and is not the waveform of SHM itself.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
