Study Notes
Quantum Physics Overview
- Quantum physics is a fundamental branch of physics that deals with the behavior of matter and energy at the smallest scales of the universe.
- It has revolutionized our understanding of the physical world, challenging classical physics and introducing a framework that often defies classical intuitions.
Historical Development of Quantum Physics
- Quantum physics emerged in the early 20th century as a response to the limitations of classical physics, which had been highly successful in describing the macroscopic world but failed to explain phenomena at the atomic and subatomic levels.
- Key developments in the historical timeline of quantum physics include:
- Planck's Quantum Hypothesis (1900): Max Planck proposed that energy is quantized in discrete packets or "quanta" when explaining blackbody radiation, marking the birth of quantum theory.
- Einstein's Photoelectric Effect (1905): Albert Einstein extended Planck's ideas by explaining the photoelectric effect, where light striking a metal surface emits electrons, and introduced the concept of photons, quantized packets of light energy.
