Unformatted text preview: TIE—Planar TWaxes in a Slit Experiment - 3 A planarwaxe is ineident an a single slit and farms a difﬁaetian pattern an a sereen. The pattern has a eentral, sereﬂkarder maximum and a number af see IZIﬂIIlEI'jF maxima. The ﬁrst-arder maximum is farmed in a direetian Where light ﬁam the tap third {a} af the slit eaneels light ﬁam the middle third {h}. The intensity af the ﬁrst-arder maximum is thus due :3an tn the hattam third af the light thraugh the slit {e} and is therefare raughljr 1i“? af the intensity I sf the eentral maximum. TWhat is the intensity af the seeand-arder maximum? .Inmnul h'l'mtruatd'llm' fl. 1— smite-add: ,r-r‘” '3! JI'H IIIII e --" I“! -"|" r' a ﬁn: s-‘eur _..-- x- a. .'

The seeand-arder maximum is farmedwhen light ﬁam the tap ﬁfth eaneels the seeand ﬁfth af the light passing thraugh the slit, as daes light farm the third and fauith ﬁfth. The seeand-arder maximum is thus due tn the hattam ﬁfth af the light passing thraugh the slit. Eeeause the intensity af light is prepartianal tn the square ef the eleetrie ﬁeld, the intensity af the seeand-arder maximum is raughljr I i“ 25 af the ineident intensity. ...
