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.
Photon energy measurement is the process of determining the energy of photons, which is crucial for applications in fields like spectroscopy and quantum mechanics. The energy of a photon is directly proportional to its frequency and can be calculated using Planck's constant and the speed of light.
Monochromatic light refers to light of a single wavelength or color, often produced by lasers or specific filters. It is crucial in scientific applications like spectroscopy and interferometry, where precise wavelength control is needed for accurate measurements.
Absorption and emission are fundamental processes in which atoms and molecules interact with electromagnetic radiation, absorbing energy to transition to higher energy states and emitting energy as they return to lower energy states. These processes are crucial in understanding phenomena such as spectroscopy, thermal radiation, and the behavior of stars and other astronomical objects.
