Chapter 17: Introduction to Quantum Mechanics
17.1 Quantum Mechanics Overview Quantum mechanics is the branch of physics that deals with the behavior of particles at the atomic and subatomic levels. It emerged in the early 20th century as a response to the limitations of classical mechanics and electromagnetism, which failed to describe the observed behavior of particles at the microscopic scale.…

Planck’s Constant
Introduction Planck’s constant, denoted by , is a fundamental constant of nature that plays a central role in the theory of quantum mechanics. It is named after the German physicist Max Planck, who first proposed its existence. Planck’s constant is a measure of the granularity of the physical world at the microscopic level, and it…

Optics
Introduction Optics is a branch of physics that studies the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behavior of visible, ultraviolet, and infrared light. Nature of Light Light is an electromagnetic wave, and its speed in a vacuum…

Quantum Mechanics
Introduction Quantum Mechanics is the branch of physics that describes the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles. It is one of the fundamental theories of physics, alongside General Relativity, and has been remarkably successful in predicting experimental results. Wave-Particle Duality One of the cornerstone concepts in…

Wave-Particle Duality
Introduction Wave-particle duality is a key principle in quantum mechanics that proposes that all particles exhibit both wave and particle properties. This concept is a fundamental departure from classical physics, where particles and waves are separate entities. De Broglie Hypothesis The concept of wave-particle duality was first introduced by Louis de Broglie in 1924. He…

Young’s Double-Slit Experiment
Introduction Young’s double-slit experiment is a famous experiment in physics that demonstrates the wave nature of light and forms the basis of the concept of interference. It was first performed by the British scientist Thomas Young in 1801. The Experiment In Young’s double-slit experiment, a beam of light is shone through two closely-spaced slits onto…
