The De Broglie wavelength is a fundamental concept in quantum mechanics that describes the wave-like behavior of particles, asserting that every moving particle or object has an associated wavelength inversely proportional to its momentum. This concept bridges classical and quantum physics, highlighting the dual nature of matter and laying the groundwork for wave-particle duality and quantum mechanics as a whole.

Quantum mechanics is a fundamental theory in physics that describes the physical properties of nature at the smallest scales, such as atoms and subatomic particles. It introduces concepts like wave-particle duality, uncertainty principle, and quantum entanglement, which challenge classical intuitions about the behavior of matter and energy.

Momentum is a vector quantity that describes the quantity of motion an object has, calculated as the product of its mass and velocity. It is a conserved quantity in isolated systems, meaning the total momentum remains constant unless acted upon by external forces.

Classical physics encompasses the principles and theories developed before the advent of quantum mechanics and relativity, primarily focusing on macroscopic phenomena. It includes foundational laws and concepts that describe the motion of bodies, forces, energy, and the properties of matter and waves in a deterministic framework.

Quantum physics is the branch of physics that deals with the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles. It fundamentally challenges classical notions of determinism and locality, introducing concepts like wave-particle duality and quantum entanglement that have profound implications for technology and our understanding of reality.

Wave-particle duality is a fundamental concept in quantum mechanics that describes how every particle or quantum entity exhibits both wave and particle properties. This duality is exemplified by experiments such as the double-slit experiment, where particles like electrons create interference patterns, a characteristic of waves, yet also behave as discrete particles when observed.
