Particles are not exclusively found where waves are. The behavior of particles in quantum mechanics is described by wave functions, which are mathematical representations that exhibit wave-like properties. However, it is important to note that a wave function is not a physical wave in the classical sense but rather a mathematical tool used to describe the probabilistic behavior of particles.
The wave function describes the probability distribution of finding a particle in different locations. In some cases, this distribution may exhibit wave-like patterns, such as interference and diffraction, similar to what is observed with classical waves. However, the wave function does not imply that particles are physically spread out like waves.
When a measurement is made, the wave function "collapses" to a specific outcome, and the particle is found at a particular location. This localization is consistent with the particle-like behavior we typically associate with classical objects.
Therefore, while the behavior of particles can be described using wave functions and exhibit wave-like phenomena, it does not mean that particles are only found where waves are present. Particles can be localized at specific positions, and their behavior is a combination of wave-like and particle-like characteristics.
