Q. Which type of oscillation can be defined by a single harmonic function? Answer:
Harmonic oscillation
Notes: Harmonic oscillation is defined by a single harmonic function, often represented by either a sine or cosine function as y = a*sin(wt) or y = a*cos(wt). This phenomenon is frequently found in nature and physical systems, such as pendulum motion, spring motion, and even in atomic and subatomic particle behaviors.
