Can we recombine the seven spectral colors to obtain white light? Justify your answer.

 Yes we can recombine the seven colors.

White light passes through a prism, it disperses into seven spectral colours. When these colours fall on another prism 2 placed in inverted position, then the colours recombine into white light.
