In optical physics, laser detuning is the tuning of a laser to a frequency that is slightly off from a quantum system's resonant frequency.When used as a noun, the laser detuning is the difference between the resonance frequency of the system and the laser's optical frequency (or wavelength).
Bass guitarist and youtuber Charles Berthoud also makes extensive use of detuners, generally on a LeFay D-Tuner (which as the name hints was designed with a detuner on each string). Adrian Legg is a popular guitarist making use of rapid tuning changes. He was prominent in the late 1980s. The idea may have originated from the double bass extenders.
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
Some instruments, such as telescopes and sea navigation instruments, have had military applications for many centuries. However, the role of instruments in military affairs rose exponentially with the development of technology via applied science, which began in the mid-19th century and has continued through the present day.
Instrumental analysis is a field of analytical chemistry that investigates analytes using scientific instruments. Block diagram of an analytical instrument showing ...
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
Historically, the definition of a scientific instrument has varied, based on usage, laws, and historical time period. [1] [2] [3] Before the mid-nineteenth century such tools were referred to as "natural philosophical" or "philosophical" apparatus and instruments, and older tools from antiquity to the Middle Ages (such as the astrolabe and pendulum clock) defy a more modern definition of "a ...
Each instrument used in analytical chemistry has a useful working range. This is the range of concentration (or mass) that can be adequately determined by the instrument, where the instrument provides a useful signal that can be related to the concentration of the analyte. [1] All instruments have an upper and a lower working limit.
