In physics, waves are not made up of more fundamental objects in the same way that particles are composed of more fundamental particles. Waves are a fundamental concept in physics that describe the propagation of energy or disturbances through a medium or through space.
In classical physics, waves are typically described mathematically by wave equations, such as the wave equation for light or the wave equation for sound. These equations govern the behavior of waves and describe how they propagate, interact, and interfere with each other.
In the context of quantum mechanics, waves are also fundamental, but they are often associated with the wave-like nature of particles. This is known as wave-particle duality, where particles exhibit both particle-like and wave-like behavior.
For example, in quantum mechanics, particles such as electrons and photons can be described by wavefunctions, which are mathematical functions that exhibit wave-like properties. These wavefunctions are solutions to the Schrödinger equation, a fundamental equation in quantum mechanics.
However, it's important to note that these wavefunctions do not represent physical waves in the same way that classical waves do. They are mathematical objects that contain information about the probability distribution of finding a particle at different locations or with different properties.
In summary, waves in physics are fundamental concepts that describe the propagation of energy or disturbances, and they are not typically composed of more fundamental objects like particles are. However, in quantum mechanics, particles can exhibit wave-like behavior described by wavefunctions, which are mathematical objects that represent the probability distribution of finding a particle.
