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-.
Fr.: jauge transverse
Same as the → Coulomb gauge.
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.
Fr.: vitesse transverse
Same as → tangential velocity.
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 Zeeman effect
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.
