    Question

    Which color of light experiences the most bending when

    it passes through a prism and separates from white light?
    A Red Correct Answer Incorrect Answer
    B Orange Correct Answer Incorrect Answer
    C Yellow Correct Answer Incorrect Answer
    D Violet Correct Answer Incorrect Answer

    Solution

    When white light passes through a prism, it undergoes a process known as dispersion, where it is split into its constituent spectrum of colors. This happens because light of different colors has different wavelengths, and each wavelength bends at a slightly different angle when it passes through the prism due to variations in the speed at which they travel through the glass. Among all the colors, violet has the shortest wavelength and hence it bends the most, resulting in its position at one end of the visible spectrum. Conversely, red light, which has the longest wavelength, bends the least. This varying degree of bending creates the range of colors seen in a dispersion spectrum.
