Cathode Rays and Some Analogous Rays . , and under con-ditions which preclude the possibility of an oscillatory discharge. No shadow isproduced if the cone of cathode rays proceeding from C is diverted by the influenceof an external magnet from falling on the anticathode A. It is therefore clearly dueeither to cathode rays reflected at A, or to some other i-ays, resembling cathode rays,which are originated at A under the impact of the cathode rays from C.^ Specularreflexion of cathode rays is not known to exist, and has not been observed in any ofthese tubes. No trace is seen of any blue cone
Cathode Rays and Some Analogous Rays . , and under con-ditions which preclude the possibility of an oscillatory discharge. No shadow isproduced if the cone of cathode rays proceeding from C is diverted by the influenceof an external magnet from falling on the anticathode A. It is therefore clearly dueeither to cathode rays reflected at A, or to some other i-ays, resembling cathode rays,which are originated at A under the impact of the cathode rays from C.^ Specularreflexion of cathode rays is not known to exist, and has not been observed in any ofthese tubes. No trace is seen of any blue cone or beam that might be a geometricalprolongation of the reflected cathode cone or beam. If reflexion is here operative, itis diffuse, not specular. But if specular, it differs from ordinary specular reflexion intwo respects: (1) the shadows have no penumbra but are sharply defined, eventhough the anticathode surface is relatively large ; (2) the distribution of the raysdiffers from that of ordinary specular reflexion.
