    Correct Answer
    E. Umbra
    Explanation
    The darkest part of a shadow is called the umbra. This is the region where the light source is completely blocked, resulting in no light reaching the surface. In contrast, the penumbra is the partially shaded area surrounding the umbra, where some light is still able to reach. The pendulum and dark side are unrelated to shadows and do not refer to the darkest part.

    What is the breaking of white light into all the colors of the visible spectrum?

    • A.

      Diffraction

    • B.

      Refraction

    • D.

      Spectrum

    Correct Answer
    A. Diffraction
    Explanation
    Diffraction is the process of breaking white light into all the colors of the visible spectrum. When light encounters an obstacle or passes through a narrow slit, it bends or spreads out, causing the different wavelengths of light to separate and create a spectrum of colors. This phenomenon is known as diffraction. Refraction refers to the bending of light as it passes through different mediums, while reflection is the bouncing back of light from a surface. Spectrum refers to the range of colors that make up white light.
