Wave interference is the phenomenon that occurs when two or more waves overlap and combine to form a new wave pattern, which can result in areas of increased amplitude (constructive interference) or decreased amplitude (destructive interference). This principle is fundamental in understanding various physical phenomena, including sound, light, and water waves, and is crucial in technologies such as noise-canceling headphones and optical instruments.

wave interference

Resonance is a phenomenon in which a system oscillates with greater amplitude at specific frequencies, known as its natural frequencies, when subjected to an external force. This effect occurs when the frequency of the external force matches one of the system's natural frequencies, leading to a significant increase in energy transfer and amplitude of oscillation.
