    Question

    The sky appears blue due to:

    A.

    Refraction

    B.

    Reflection

    C.

    Scattering

    D.

    Dispersion

    Correct option is C

    The blue color of the sky is due to a phenomenon known as Rayleigh scattering. This occurs when sunlight interacts with the molecules and small particles in Earth's atmosphere. Sunlight is made up of different colors, each with varying wavelengths. Blue light has a shorter wavelength and is scattered more easily by the gases and particles in the atmosphere compared to other colors like red, which have longer wavelengths.
