  • Let's explore why the sky is blue, why the sunset/sunrise is red, why are clouds white. It's all due to scattering of light by the molecules of our atmosphere.

    Excellent explanation in simplest possible way. Relationship between particle size and light wavelength was explained absolutely perfect. Even in standard textbooks such beautiful explanation is not provided. They are just confusing with technical terms and not clarifying the actual differences and concepts. Some book authors are not even able to explain the difference between Scattering and Dispersion.
    Excellent effort by the creator 👌👌👌

    • @31sohampandeyxi-a92
      @31sohampandeyxi-a92 3 года назад

      It is so because gold light is incident on the particles and also it doesn't have spectrum of VIBGYOR, so after scattering it will appear gold in colour.
