Quantum physics is a branch of science that studies the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles. It introduces concepts like wave-particle duality, quantization of energy, and the uncertainty principle, which challenge classical physics.Quantum physics explains phenomena outside the scope of classical mechanics, resulting in technological advances such as semiconductors, lasers, and quantum computing.
