Reststrahlenn.

Brit.

/rɛstˈʃtrɑːlən/, U.S.

/rɛstˈʃtrɑlən/

Forms: 1800s– Reststrahlen, 1900s– Restrahlen (nonstandard). Also with lower-case initial.

Origin: A borrowing from German. Etymon: German Reststrahlen.

Etymology: < German Reststrahlen residual rays (H. Rubens and E. F. Nichols 1897, in Ann. der Physik u. Chem. 60 442) < Rest remainder (see rest n.³) + Strahlen , plural of Strahl ray (see streale n.). Compare later Reststrahl n.

Physics.

Electromagnetic radiation which is selectively reflected from the surface of a crystalline solid when the frequency of the incident radiation is approximately equal to the vibrational frequency of the ions constituting the solid. Frequently attributive.
