91Optical coating — Optically coated mirrors and lenses. An optical coating is one or more thin layers of material deposited on an optical component such as a lens or mirror, which alters the way in which the optic reflects and transmits light. One type of optical… …
92Electronic amplifier — A practical amplifier circuit An electronic amplifier is a device for increasing the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In… …
93Photolithography — For earlier uses of photolithography in printing, see Lithography. For the same process applied to metal, see Photochemical machining. Photolithography (or optical lithography ) is a process used in microfabrication to selectively remove parts of …
94Uncertainty principle — In quantum physics, the Heisenberg uncertainty principle states that locating a particle in a small region of space makes the momentum of the particle uncertain; and conversely, that measuring the momentum of a particle precisely makes the… …
95De Broglie hypothesis — In physics, the de Broglie hypothesis (pronounced /brœj/, as French breuil, close to broy ) is the statement that all matter (any object) has a wave like nature (wave particle duality). The de Broglie relations show that the wavelength is… …
96Rail adhesion — Driving wheel of steam locomotive The term adhesion railway or adhesion traction describes the most common type of railway, where power is applied by driving some or all of the wheels of the locomotive. Thus, it relies on the friction between a… …
97Electron — For other uses, see Electron (disambiguation). Electron Experiments with a Crookes tube first demonstrated the particle nature of electrons. In this illustration, the profile of the cross shaped target is projected against the tube face at right… …
