    What happens when a beam of pure white light passes through a prism?
    Question

    What happens when a beam of pure white light passes through a prism?

    A.

    The ray will be reflected

    B.

    The ray will converge

    C.

    The beam will flicker

    D.

    The ray will be scattered

    Correct option is D

    The  Correct Answer is: (d) The ray will be scattered

    • When a beam of pure white light passes through a prism, the light undergoes dispersion, separating into its constituent colors (spectrum) due to the different degrees of refraction experienced by different wavelengths of light.

    Information Booster:

    • Dispersion occurs because the refractive index of the prism material varies with wavelength.
    • Violet light, having the shortest wavelength, bends the most, while red light, with the longest wavelength, bends the least.
    • This creates a spectrum of colors, known as VIBGYOR (Violet, Indigo, Blue, Green, Yellow, Orange, Red).
