constructive interference
  اندرزنش ِ سازنده   
andarzaneš-e sâznadé

Fr.: interférence constructive   

An → interference process in which the → amplitude of the resultant wave is greater than that of either individual waves. See also → destructive interference.

Constructive, from M.Fr. constructif or from M.L. constructivus, from L. construct-, p.p. stem of construere "to heap up," from → con- + struc- variant stem of struere "to build," → structure; → interference.

Andarzaneš, → interference; sâzandé "constructive," from sâxtan, → structure.

destructive interference
  اندرزنش ِ ویرانگر   
andarzaneš-e virângar

Fr.: interférence destructive   

An → interference process in which the → amplitude of the the amplitude of the resultant wave is less than that of either individual waves. See also → constructive interference.

Destructive, from O.Fr. destructif, from L.L. destructivus, from destruct-, p.p. stem of destruere, from → de- + struere "to build," → structure; → interference.

Andarzaneš, → interference; virângar "destructive," from virân, "destroyed, ruined."

interfere
  اندرزدن   
andarzadan

Fr.: interférer   

Physics: To cause → interference.

Interfere, from M.Fr. entreferer "to strike each other," from entre, → inter-, + ferir "to strike," from L. ferire "to knock, strike."

Andarzadan, from andar, → inter-, + zadan "to strike, beat," from Mid.Pers. zatan, žatan; O.Pers./Av. jan-, gan- "to strike, hit, smite, kill" (jantar- "smiter"); cf. Skt. han- "to strike, beat" (hantar- "smiter, killer"); Gk. theinein "to strike;" L. fendere "to strike, push;" Gmc. *gundjo "war, battle;" PIE *gwhen- "to strike, kill."

interference
  اندرزنش   
andarzaneš

Fr.: interférence   

The phenomenon occurring when two or more waves of the same → frequency having a constant → phase difference traverse simultaneously in the same region of a medium and cross each other. In the region of superposition, the the resulting wave intensity is different from the sum of intensities due to individual waves at that point. This phenomenon proved the validity of the wave theory of light. See also → constructive interference, → destructive interference, → interference fringe, → Young's experiment, → wave theory of light.

Interference, from → interfere + -ence a noun suffix equivalent to -ance, corresponding to the suffix -ent in adjectives.

Andarzaneš, verbal noun of andarzadan, → interfere.

interference filter
  پالایه‌ی ِ اندرزنشی   
pâlâye-ye andarzaneši

Fr.: filtre interférentiel   

A filter that uses the phenomenon of optical interferences between plane-parallel semi-transparent reflectors to transmit light selectively over a narrow wavelength band.

interference; → filter.

interference fringe
  فریز ِ اندرزنشی   
fariz-e andarzaneši

Fr.: franges d'interférence   

One of the alternating bright or dark bands produced by optical interference.

interference; → fringe.

interference order
  رایه‌ی ِ اندرزنش   
râye-ye andarzaneš

Fr.: ordre d'interférence   

order of interference.

interference; → order.

interference pattern
  الگوی ِ اندرزنش   
olgu-ye andarzaneš

Fr.: figure d'interférence   

A wave pattern that results when two or more waves interfere with each other, generally showing → interference fringes. In acoustics, the interference pattern appear as the effect of → beats.

interference; → pattern.

order of interference
  رایه‌یِ اندرزنش   
râye-ye andarzaneš

Fr.: ordre d'interfrérence   

A whole number which characterizes a particular position of an interference fringe according to whether there is interference arising from one, two, three, etc. wavelength difference of path. Same as → interference order

order; → interference.
