cident angle LIN increases, theangle EIP also increases, while lEPdiminishes. Hence, according as thedirection of the ray LI tends to be-come parallel with the face AB, doesthis ray tend to emerge at the secondface. Let LI be now parallel to AB, theangle r is then equal to the criticalangle / of… … Fig. 494. 520 On Light. [546- therefore A = r + /; therefore also P^ = l + i\ for in this case r = l. Hence, ifA = 2/ or is >2/, we shall have i = / or >/, and therefore the ray would notemerge at the second face, but would be parallel to AC or would undergointernal reflection, and emerge at…
