he angles of incidence and of emergence areequal. The angle of minimum deviation may be calculated when the incidentangle and the refracting angle of the prism are known. For when thedeviation is a minimum, then since the angle of emergence ;•is equal to theincident angle /(fig. 494),r must… … If the minunuiterior to the trianjj -550] Measurement of tJie Rcfractiic Index of Liquids. 521 whence d=2i — A.
