Molecular vibration refers to the periodic motion of the atoms within a molecule, which occurs when the molecule absorbs energy, leading to changes in bond lengths and angles. This phenomenon is fundamental to understanding molecular spectroscopy, chemical reactions, and the thermal properties of substances.
Concept
Laser ablation is a precise material removal process that uses a highly focused laser beam to vaporize or remove material from a solid surface, often used in manufacturing, medical, and scientific applications. It offers advantages such as minimal thermal damage, high precision, and the ability to process a wide range of materials, including metals, ceramics, and biological tissues.
Concept
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.
Concept
Nuclear physics is the branch of physics that studies atomic nuclei and their constituents and interactions, focusing on understanding the fundamental forces and particles that govern nuclear reactions and stability. It has significant applications in energy production, medical imaging, and understanding the universe's elemental composition.
