Why is the sky blue and the sun yellow? (Hindi) | Human eye | Physics | Khan Academy

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 👌👌👌

7 : 06 can u explain it tht why the particles removed the blue ray plzzz reply

[@Sagar-wn1po]

Due to Reyleigh effect, scattering is inversely proportional to wavelength of light. Violet has smallest wavelength.

[@Sub.inspector753]

Scattering concept is mystery to me, but it all clear my doubts, with your experiment and explanation. Thank you very much 🙏🙏🙏.

app ne to bola tha agar earth me atmosphere nehi hoga to Hume other side black dikhega par ek room me to atmosphere hoti he to mera sawal he ki Hume other side kyu black dikhti he plz ans my question

[@scienceprojectmanagement9350]

Because the light of torch is very less and can't scatter in the whole room but if you take aa big light resource like LED bulb it will scatter in the whole room..

[@ShivamKumar-fm8ev]

Sir app bahut bahut hi accha padhate hai ... App ki voice bhi bahut acchi hai app mera pura doubt and concept puri Tarah se clear Kar de te hai or thanks sir app bahut hi easy way me padhate hai aur app ka background bhi bahut accha hai .....

[@arshad723]

thanks team KHAN ACADEMY AND OUR RAM SIR now i have clarity in my topic and i really loved the video

[@searchtrending]

That is not more and less colour but concept is that Light having shorter wavelength are more effective in scattering of blue Light.

[@jaishriram4340]

QUESTION:-sir, the particles of gold are also bigger than the wavelength of visible light then why don't they appear white?

[@31sohampandeyxi-a92]

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.

[@shehlachaudhary.804]

But why some times the colour of clouds is black?

[@asifalam5519]

May be aryan due the presence of water vapour, pollutants particles, some small earthy particles and various types of polluted gases like co, co 2, ch4 and so 2. All mix together to form a concentrated heavy water droplet to make a dense black clouds😅 well it's totally my thinking brother.. I don't know exactly what's the reason.
