8A back again by the flint glass,giving a nett deviation of -424A. The C and F rayswill therefore emerge parallel, both having suffered adeviation of -424A. DISPERSION 37 The deviation of the D ray would be 1-060A--635A,i.e. *425A. This is very nearly equal to the deviationof the C and F rays, but… … FLINT Fig. 23. small enough to be negligible, but it is possible to arrangethree prisms of different dispersive power so that threecolours have exactly the same deviation. Even thenthe deviation of the remaining colours would not beexactly the same, but the dispersion would be verymuch smaller than…
