Absorption (acoustics) — Absorption refers to the absorption of sound waves by a material. The absorption is the missing piece , when comparing the total reflected and transmitted energy with the incident energy. It is the property of a material that changes acoustic… … Wikipedia
Absorption spectroscopy — An overview of electromagnetic radiation absorption. This example discusses the general principle using visible light as a specific example. A white beam source – emitting light of multiple wavelengths – is focused on a sample (the complementary… … Wikipedia
Absorption wavemeter — The Absorption wavemeter is a simple device for the measurement of radio frequency energy at different frequencies. The device can be used by the users of radio equipment to check the approximate frequency of a strong signal source, and also to… … Wikipedia
absorption edge — Physics. a discontinuity in the graph of the absorption coefficient of a substance plotted against the wavelength of x rays being absorbed, representing the minimum energy necessary to free electrons from particular shells of the atoms of the… … Universalium
Frequency-resolved optical gating — In optics, frequency resolved optical gating (FROG) is a derivative of autocorrelation, but is far superior in its ability to measure ultrafast optical pulse shapes. Further, it can determine the phase of the pulse.In the most common… … Wikipedia
