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.

    Spectrum

    This section covers the dispersion of light, the visible spectrum, and the process of recombination, highlighting Sir Isaac Newton's experiments.

    Learning Practice

  • 6.1

    Dispersion Of Light

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

    Learning Practice

  • 6.2

    Spectrum

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

    Learning Practice

  • 6.3

    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.

    Learning Practice

  • 6.4

    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.

    Learning Practice

  • 6.5

    Newton’s Experiment

    Newton’s Experiment illustrates how white light can be separated into multiple colors using a prism and subsequently recombined.
