In point of fact,it is found that one of them tendsto penetrate the glass, and theother to be reflected from it. Ata certain angle, called the angleof complete polarization, this ten-dency produces a complete separration of the two components ofthe ray. One component, asshown in Fig. 376, penetrates the material of the mir-ror, and is transmitted as a refracted ray; the other isreflected. This reflected ray contains only vibrations inone plane. It constitutes what is called a beam of planepolarized light. To show that it consists of vibrations ina single plane only, a second mirror may be interposed inits path at the angle of polarization. If this mirror beturned, as shown in Fig. 377, it will reflect the polarized. 404 THE OUTLINES OF PHYSICS ray because the vibrations meet its surface in the samemanner as in the case of the first mirror. If, however, itbe turned through 90°, the ray will enter the mirror, and
