    Q1. Why does the ocean appear blue?

    • A) Because the sunlight falling on it is refracted
    • B) Because the sunlight falling on it is scattered
    • C) Because the sunlight falling on it is reflected
    • D) Because the sunlight falling on it is absorbed

    Answer: Because the sunlight falling on it is scattered

    Explanation: The ocean appears blue primarily because water molecules selectively absorb longer wavelengths (red, orange) and scatter shorter wavelengths (blue) — Rayleigh scattering also contributes.
