| 释义 | refraction noun[ U ] physics specializeduk /rɪˈfræk.ʃən/ us /rɪˈfræk.ʃən/ the fact of light or sound being caused to change direction or to separate when it travels through water, glass, etc. 折射 absolute index of refraction a calculation of the relationship between the speed of light moving through a medium(= substance) and the speed of light in a vacuum(= an area with no matter in it): 绝对折射率 So how do you calculate the absolute index of refraction? angle of refraction the angle that a beam of light or other energy that is refracted by a surface makes with a line vertical to that surface: 折射角 White light splits into a colour spectrum during refraction because each constituent wavelength's angle of refraction is different.

Examples of refractionrefraction Furthermore, in the shallow water, refraction implies that loci of constant phase are usually nearly parallel to the local coast line. The propagation characteristics and wave damping can be examined from the real and imaginary components of the index of refraction. Depth measurements were made by reading from the calibrated scale on the fine focusing adjustment without correction for refraction. A further innovation can be found in the detailing of surface textures, especially reflections and refractions.

In this limit, the imaginary part of the collision frequency can be ignored and the index of refraction is unity. About 30% of laser energy was lost in the results of reflection and refraction effects. When the ratio is larger than one, the free and bound electrons are contributing with the same sign to the index of refraction. A well-known example is in the refraction of a shock at the edge of a free jet which is diffusing into an initially still atmosphere. The objective of the present paper is to formulate the appropriate definition of shock impedance when refraction takes place at an arbitrary angle of incidence. The so-calledphenomenon of sonic cut-off is an example of precursors forming by refraction in gases. At that stage many can be discharged to an optometrist for final refraction. The waves are refracted according to the ordinary refraction law deduced for non-moving magnetoactive plasma. The results reaffirm that bound electrons can strongly influence the index of refraction of numerous plasmas over a broad range of soft x-ray wavelengths. Also, for two-point ray tracing the index of refraction must be interpolated. See all examples of refraction These examples are from corpora and from sources on the web.
