In physics, waves are not typically composed of more fundamental objects in the same way that matter is composed of atoms or molecules. Waves are rather a fundamental concept that describes the propagation of energy or disturbances through a medium or space.
In classical physics, waves can be described as the collective behavior of many individual particles or oscillators. For example, in a water wave, the motion of individual water molecules combines to create the overall wave pattern. However, these individual molecules are not considered the fundamental building blocks of the wave itself.
In the context of quantum mechanics, waves are described by wavefunctions, which are mathematical functions that represent the probability amplitudes of finding a quantum entity in different states. Quantum waves, such as electromagnetic waves or matter waves, are not composed of more fundamental objects but are instead intrinsic properties of the quantum entities themselves.
It's worth noting that in some theories, such as string theory, the fundamental entities are described as vibrating strings or higher-dimensional objects that can exhibit wave-like behavior. However, these theories go beyond the scope of classical physics and introduce concepts from quantum field theory and higher-dimensional physics.
In summary, waves in physics are typically fundamental concepts that describe the behavior of energy or disturbances, rather than being composed of more fundamental objects themselves.
