transverse
  تراگذر   
tarâgozar (#)

Fr.: transverse   

Lying or extending crosswise or at right angles to something. → transverse velocity; → transverse wave.

From L. transversus "turned or directed across," p.p. of transvertere "to turn across," from → trans- + vertere "to turn," cognate with Pers. gardidan "to turn, to change;" Mid.Pers. vartitan; Av. varət- "to turn, revolve;" Skt. vrt- "to turn, roll," vartate "it turns round, rolls;" O.H.G. werden "to become;" PIE base *wer- "to turn, bend."

Tarâgozar, from tarâ-trans- + gozar "passage, transit, passing," from gozaštan "to pass, cross, transit," variant gozâštan "to put, to place, let, allow;" Mid.Pers. widardan, widâštan "to pass, to let pass (by);" O.Pers. vitar- "to pass across," viyatarayam "I put across;" Av. vi-tar- "to pass across," from vi- "apart, away from" (O.Pers. viy- "apart, away;" Av. vi- "apart, away;" cf. Skt. vi- "apart, asunder, away, out;" L. vitare "to avoid, turn aside") + O.Pers./Av. tar- "to cross over;" → trans-.

transverse gauge
  گز ِ تراگذر   
gaz-e tarâgozar

Fr.: jauge transverse   

Same as the → Coulomb gauge.

transverse; → gauge.

transverse mass
  جرم ِ تراگذر   
jerm-e tarâgozar

Fr.: masse transverse   

In special relativity theory, the mass when the acceleration of a body is perpendicular to its velocity: mt = m0 / [1 - (v/c)2]1/2, where m0 is the → rest mass, v is the velocity, and c the → velocity of light. The transverse mass is identical to the → relativistic mass. See also → longitudinal mass.

transverse; → mass.

transverse velocity
  تندای ِ تراگذر   
tondâ-ye tarâgozar

Fr.: vitesse transverse   

Same as → tangential velocity.

transverse; → velocity.

transverse wave
  موج ِ تراگذر   
mowj-e tarâgozar

Fr.: onde transversale   

A wave in which the vibration or displacement takes place in a plane at right angles to the direction of propagation of the wave; e.g. electromagnetic radiation. → longitudinal wave.

transverse; → wave.

transverse Zeeman effect
  اُسکر ِ زیمن ِ تراگذر   
oskar-e Zeeman-e tarâgozar

Fr.: effet Zeeman transverse   

The → Zeeman effect when observed at right angles to the orientation of the magnetic field. Un un-displaced line is observed along with a doublet, three lines in all, with the frequencies ν and ν ± Δν. The two displaced components correspond to a plane of → polarization parallel to the external magnetic field and the un-displaced line to a plane of polarization perpendicular to this field. → longitudinal Zeeman effect.

transverse; → Zeeman effect.
