      SAT物理考试中有很多专业术语,新航道小编整理常用SAT物理专业术语即系,供大家参考。

      De Broglie wavelength

      A wavelength, given by = h/mv, which is associated with matter. Louis de Broglie proposed the idea that matter could be treated as waves in 1923 and applied this theory successfully to small particles like electrons.

      Decay constant

      A constant, , not to be confused with wavelength, that defines the speed at which a radioactive element undergoes decay. The greater is, the faster the element decays.

      Decibel

      A logorithmic unit for measuring the volume of sound, which is the square of the amplitude of sound waves.

      Deposition

      The process by which a gas turns directly into a solid because it cannot exist as a liquid at certain pressures.

      Destructive interference

      The cancellation of one wave by another wave that is exactly out of phase with the first. Despite the dramatic name of this phenomenon, nothing is “destroyed” by this interference—the two waves emerge intact once they have passed each other.

      Diffraction

      The bending of light at the corners of objects or as it passes through narrow slits or apertures.

      Diffraction grating

      A sheet, film, or screen with a pattern of equally spaced slits. Typically the width of the slits and space between them is chosen to generate a particular diffraction pattern.

      Direction

      The property of a vector that distinguishes it from a scalar: while scalars have only a magnitude, vectors have both a magnitude and a direction. When graphing vectors in the xy-coordinate space, direction is usually given by the angle measured counterclockwise from the x-axis to the vector.

      Directly proportional

      Two quantities are directly proportional if an increase in one results in a proportional increase in the other, and a decrease in one results in a proportional decrease in the other. In a formula defining a certain quantity, those quantities to which it's directly proportional will appear in the numerator.
