by Prof. Mciit/ncr 1. 2. 



The scale of the apparatus moves of itself so as to make its zero point agree with the incident 

 ray of light. The apparatus can be used without darkening the room. 



53.710. Reflection Apparatus after Stahlberg, Figure (Ztschr. f. d. phys. u. cliein. I'. 15, 



p. 73), on adjustable stand with foot-screw 1. 8. 



The hinge-pin of two metal bars carries a mirror and. perpendicular to ihc latter, a rod which 

 always forms the angle-bisector for the two bars and thus forms the axis of incidence. The luminous 

 ray along the one limb encounters the mirror and is always reflected along the other limb. The 

 apparatus can be employed for light falling from the right or (lie left.
