6. Spectrum

The chapter discusses the phenomenon of dispersion and the creation of the spectrum from white light through a prism. It explains the separation of colors based on their wavelengths and how different colors bend at varying angles, leading to a distinct order of colors known as VIBGYOR. Additionally, it describes the recombination of the colors back to white light and highlights Sir Isaac Newton's experiment that demonstrated these principles.

    Dispersion Of Light

    Dispersion is the phenomenon of splitting white light into its seven constituent colors (VIBGYOR) when it passes through a prism.

    Spectrum

    The spectrum consists of the seven colors that emerge from the dispersion of white light.

    Cause Of Dispersion

    The cause of dispersion is the variation in the speed of light of different colors in a medium, resulting in a unique refractive index for each color.

    Recombination Of Spectrum

    The recombination of the spectrum shows that white light is a combination of the seven colors produced by dispersion through a prism.
