An illustration of some of the optical devices available for laboratory work in England in 1858. An optical instrument is a device that processes light waves (or photons), either to enhance an image for viewing or to analyze and determine their characteristic properties.
Phase shift through a beam splitter with a dielectric coating. Beam splitters are sometimes used to recombine beams of light, as in a Mach–Zehnder interferometer.In this case there are two incoming beams, and potentially two outgoing beams.
Physical optics is also the name of an approximation commonly used in optics, electrical engineering and applied physics.In this context, it is an intermediate method between geometric optics, which ignores wave effects, and full wave electromagnetism, which is a precise theory.
Experimental music is a general label for any music or music genre that pushes existing boundaries and genre definitions. [1] Experimental compositional practice is defined broadly by exploratory sensibilities radically opposed to, and questioning of, institutionalized compositional, performing, and aesthetic conventions in music.
