Best channel for class 10th physics
Not best!!!!! Try physicswallah
@@yadavrohit52477 i do watch physics wallah he has great knowledge but animation makes it easy to memorize and help us to understand better 😇😇
Yeah
Sahi baat hai
Y'a bro but physicswallah also best
If youtube was a library , then khan academy would be its most golden shelf
Learning:
1.Twinkling of star is just changing the brightness of star continously.
Star appears very small in size because they are very far away from us.
2.Our environment is changing its density continuously due to various reasons like temperature,density of dust, density of gases, air.
3.Due to this reason sometimes more light rays of star come from us and sometimes less light rays. Therefore, they appear to be twinkle.
4.planets don't appear to be twinkle bcoz they look quite big with respect to stars.
5.when some parts of it dims the other part brightens.
6.due to this reason overall their brightness doesn't change.
Thanks
Thank you for the summary
Thanks to you actually!
Thanks
Thank you sir ji
Thanks bhai
As an Indian in the 80's I grew up in the middle East in 'the Indian School'. I think the worst teachers from India got exiled to the Gulf. Because I never learnt anything in science and flunked badly. What sweet irony that now we Indians are the best at explaining things in the world. I feel really sad that we had no access to the internet back then, and instructors like this who are so passionate and genuine. Who knows I might have become something very different in life 😊
oo
What a wonder way to show !! (4:04)
Khan sir is really something else 👌👌
Very nice ❤❤❤
4:57 Amazing 😊😊❤
The explanation as well as animation is best of all..
Thanks a lot!😊🙏🙏
True
I m in class 11 so I know that why stars twinkle I am really amazed by the way you explain it. You made it very easy and interesting and understandable for the learner.
Thankyou very much Khan academy
So explain me bro
It is explained in class 10th NCERT science Book chapter 11

such a great teaching style sir, so easily understood the topic, thank you so much
Your videos are amazing, but the problem is that you only teach physics. I also want to learn chemistry from you. You explain the concepts in the best way.
To be honest ... The detailed explanation I've seen so far !!!
Others just mentioned it was because atmospheric refraction but didn't tell how did it work ( especially the bright dim effect )
Thank you so much
And without wasting any time u explained it so gooodd !!!
