orbital effect
41Sokolov-Ternov effect — The Sokolov Ternov effect is the effect of self polarization of relativistic electrons or positrons moving at high energy in a magnetic field. The self polarization occurs through the emission of spin flip synchrotron radiation. The effect was… …
42Hall effect thruster — In spacecraft propulsion, a Hall thruster is a type of ion thruster in which the propellant is accelerated by an electric field. Hall thrusters trap electrons in a magnetic field and then use the electrons to ionize propellant, efficiently… …
43Shielding effect — The shielding effect describes the decrease in attraction between an electron and the nucleus in any atom with more than one electron shell. It is also referred to as the screening effect or atomic shielding.CauseIn a single electron system such… …
44Compton effect — Comp·ton effect käm(p) tən n the loss of energy and concomitant increase in wavelength of a usu. high energy photon (as of X rays or gamma rays) that occurs upon collision of the photon with an electron Compton Arthur Holly (1892 1962) American… …
45paschen-back effect — ˈpäshənˈbäk noun Usage: usually capitalized P&B Etymology: after Friedrich Paschen died 1947 and Ernst Back b1881 German physicists : a limiting stage of the Zeeman effect which occurs as the magnetic field causing it is greatly increased and in… …
46Random orbital sander — Random orbit sanders, also called Dual Action or D.A. sanders (referring to the rotation of the disk and the head) are hand held power sanders where the action is a random orbit. They were first introduced in the early 1990s and quickly became… …
47Paschen-Back effect — /pah sheuhn bahk /, Physics. a splitting of spectral lines observed when the source of a radiation is subjected to a strong magnetic field, caused when the vectors associated with the spin and orbital angular momentum exhibit individual rather… …
48chemical bonding — ▪ chemistry Introduction any of the interactions that account for the association of atoms into molecules, ions, crystals, and other stable species that make up the familiar substances of the everyday world. When atoms approach one another …
49spectroscopy — spectroscopist /spek tros keuh pist/, n. /spek tros keuh pee, spek treuh skoh pee/, n. the science that deals with the use of the spectroscope and with spectrum analysis. [1865 70; SPECTRO + SCOPY] * * * Branch of analysis devoted to identifying… …
50Orbit — This article is about orbits in celestial mechanics, due to gravity. For other uses, see Orbit (disambiguation). A satellite orbiting the Earth has a tangential velocity and an inward acceleration …
