Amazingly explained.... Very joyful voice... Hats off..... It's a kind of voice that makes your mind to think "ab aage kya hoga? "
I searched a lot but this is the best and perfect explanation. It covers the best examples of Tyndall effects.
Tysm❤️ sir for your incredible explanation.... I got all the concepts...
At last I wanna say just one thing...
You're just awesome...😊😊
Hii
Ram Bhaiya you are amazing thank you very much for this explanation
Really love your lectures♥️♥️ Please come up with Olympiad level videos and questions also.
At any institutions in which me and my friends study they don't know any experiment,only know due to refraction of light this is happen but you give a truth experiment which helps to believe and learn frequently🙏🙏🙏❤️❤️❤️
Experiments simple thee pr concept but excellent samjh a gya
Why youtube not recomed this chanel?
And also do not show theirvideo on searching
As this video is not optimised for SEO, & Khan Academy works for students... Thet don't waste money on promotion like other companies
I was totally confused about this concept..... but now u have totally removed my confusion thanks a lot sir 👍👍👌👌 🤗🤗🤗

For clearing my doubts 🙏🙏
Perfect...explainaton...👍👏 *TYSM*
I am devoid of words to admire your way of teaching! Highly impressive!
Maja aa gya ..Is video ek sath kayi doubt clear kar diye.. Mujhe aaj tk samjh nhi aaya tha ki voilet ki wavelength sabse km h fir b hame sky blue kyo dikhta h..Thanku for clear by doubt.
Best best best lecture ever your teaching style is awesome Thanks a lot aapko meri duaen !!! 😇😇😇
You deserve a lot of respect from my side. Best 👍💯 explanation.
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 👌👌👌
What an amazing video. All doubts cleared!!. This is what I was looking for.
Lovely video
Keep the good work going
RAM Amazing 😉
Your experiment was amazing.
I can't praise your explanation in words.
Simply Outstanding
Scattering concept is mystery to me, but it all clear my doubts, with your experiment and explanation. Thank you very much 🙏🙏🙏.
Awesome video. Keep making more.🙂
Pad le bro

This channel has helped me clear all my doubts
Thank you and great work
Your voice gives amazing explanation. Bless
Awesum
Sir one more question how the all colours lights are separated in a 🌈
Ok
Good question
Due to refraction of light
Due to dispersion of light and internal reflection by water droplets present in atmosphere
@@ajsiblings3616 right
In this video I understand everything about scattering of light so thank you ram sir
This video is really amazing.Hats off to you sir for this wonderful explanation.
7 : 06 can u explain it tht why the particles removed the blue ray plzzz reply
Due to Reyleigh effect, scattering is inversely proportional to wavelength of light. Violet has smallest wavelength.
Thanks
Marvellous !!!!concept & ideas to teach
Hatsoff bro, very good Explaination plus voice
QUESTION:-Why then the air around us doesn't appear blue?
But sir then why do we find red algae in greater depths..... It has somewhat opposite explanation.......
Weldone, bro what a explanation ek baar me samaj me agayay
Kya explanation dete hai aap sir. . Or Kya experiment hai!!👍👍👌👌
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
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..
But why some times the colour of clouds is black?
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.
Nice 😊
Accha hmmmm
Can u tell me why
That's The Great Explainatation Ever....Thank You ♥️ Jo Bhi Video Pura Dekh Lega Wo Jindagi Bhar Abb Ye Question Ke Answers Nhi Bhuul Payeaga.... Thank You Again Sir....🙏🙏
Its very impresive and excellent video thank you for understanding our students very easily
Before last day before exam how many time people see at 2.0 x speed comment
That is not more and less colour but concept is that
Light having shorter wavelength are more effective in scattering of blue Light.
Really sir aap itna achha explain karte ho na ki even a unknow one also understands clearly ... Thank u for your effort sir we utilize it in best way....
Thaks for explaining with real experiments👌👌
QUESTION:-sir, the particles of gold are also bigger than the wavelength of visible light then why don't they appear white?
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.
Aap bhgvan ho
Best video ever to understand. Everyone should watch this.
After so many tries,i found a best teacher who explained everything in a proper way with clearing all the doughts.
Every science book can't explain the reason of the phenomenon which occur and this is my big problem and i try to find the reason of these phenomenon but i can't get a proper solution.
But ram sir through this channel clear all of my doubts.
Thanks a lot sir....🤗🤗💗💗❤❤
