Why is the sky blue? Thoroughly Explained Here!

This video describes the science of how Rayleigh scattering leads to blues and reds visible in the sky. It will incorporate ideas about white light, additive color, sun-Earth geometry, and scattering. Why is the sky blue? Search no further. Visit sites.google.com/site/dcaulfs... for more!

    great explanation, but I wish you talked more about sunrise and sunset. So do reds and oranges appear in the sky because the suns lower and light is being effected by more atmospheric scattering? i'm guessing the red light is able to evade all of the molecules in its path and reach our eyeball while the blue light hits every molecule and scatters out of our site?

    brilliant.. haven't ever even when I was studying had come across this kind of explanation to understand this concept.. beautifully explained. Cloud contains water molecules which are bigger in size than the wavelength of the light photons, hence no rayleigh effect is observed the clouds and all colour photons pass through it in a straight line and thus the clouds appears white.

    Thanks for the video. Are you approximating the relation (I ~ 1/(lambda)^4) for relatively large wavelengths like visible light? Cuz I'm getting confused over this and Planck's function for the thermal radiation which is the correct explanation in comparison to the former relation.

  • @Shrilaraune
    @Shrilaraune4 жыл бұрын

    This is amazing. I think the only thing that has me confused is the two different uses of intensity? We have intensity as in the chances of a photon entering your eye (proportional to 1/λ^4) and then we also have the intensity that decreases as photons are scattered. With the first, red light has a low intensity (well really is proportional to a lower number than say blue light) and so scatters less With the second, red light scatters less and so the intensity is higher or remains higher. Can anyone help with this?

  • @fnayo

    I think the light is being "scattered" due to electromagnetic oscillation of a molecule -- a more energetic photon will cause more oscillation to molecules that it travels near and therefore more "scattering".

    Wow this is so cool! So this is also why clouds look extremely pretty in highly polluted cities at night, yeah? All of the particles in the pollution will scatter basically every blue and green light ray (obviously not all of them, but you get the picture) and the clouds will appear almost pure red?
