In physics, a wave is not considered an object itself, but rather a disturbance or oscillation that propagates through a medium or space. It is a form of energy transfer without the physical displacement of matter as a whole. While a wave can be characterized by its properties such as wavelength, frequency, and amplitude, it does not possess a localized mass or structure like a physical object. Instead, a wave represents the motion or disturbance of particles or fields within a medium, transmitting energy from one location to another. Examples of waves include electromagnetic waves (such as light and radio waves) and mechanical waves (such as sound waves and water waves).
