gles, and therefore with different opticalpaths, hence the interference effects will not be uniform over thewhole field. In general the effects are quite complex and cannotbe discussed here, but the simple case of a uniaxial crystal cut 460 LIGHT. perpendicular to the optic axis may be considered… … Fig. 335. light may be supposed to be in a vertical plane, as indicated bythe arrovi^s. At P and Q the incident vibrations are respectivelyparallel and perpendicular to the principal sections PP and QQand travel through without change. If an analyzer is placedbeyond the crystal and set for…
