To recombine the spectrum to obtain white light, the dispersive prism and recombination prism should be in an inverted position with the dispersion prism.
Question Image

As in the figure, we observed that to obtain the white light, the dispersion prism and the recombination prism should be in an inverted position. Since the refraction produced by the other prism is identical and opposite to that produced by the first prism, it is important that the two prisms utilized for the recombination of the spectrum of white light be similar and situated in an inverted position with regard to each other.
