What formation of interference patterns by electrons is best explained using which concept?

The formation of interference patterns by electrons is best explained using the concept of wave-particle duality, a fundamental principle of quantum mechanics. When electrons are passed through a double-slit apparatus, they exhibit wave-like behavior, creating an interference pattern that suggests they are behaving as waves rather than discrete particles. This phenomenon illustrates that particles can exhibit both wave and particle characteristics, depending on the experimental setup. The interference pattern emerges as a result of the wave functions of the electrons overlapping and interacting with each other.
