at 41:50, for those who are thinking why sin o became equal to tan o, since o is very small, therefore cos o tends to 1...... that is why sin o = tan o (o= theta)

Today started this chapter Nd this part is going on..can't afford the online classes so from now no tension of physics__"🙃 Thank you so much sir ....may God bless you with health Nd wealth...(✿^‿^)
I am amazed by Sir's habit of talking like we all are right in front of him. I never feel like I am watching this online. It requires a lot of dedication towards your work to reach this this level of being absorbed in teaching. WE ALL LOVE YOU ALAKH SIR
The most attractive thing which I like in him ...that he is very natural .. specially.❤️❤️ He is not snide.., bogus ... Very energetic always in every lectures
Aap nhi teh toh sir unacademy se kaam chalaraha tah but feel nhi hua ...lkin now im confident wid YDSE thank you sir May god bless you Those wu agree sir k liye like tokho
I just watched double slit experiment experiment on RUclips via animation I Wonder If sir had the proper Apparatus the explanation would be mind-boggling I can't even imagine how amazingly sir had explained this. For those who are unable to get this experiment plz watch the real experiment what it was I am amazed this exp is growing love for physics more n more wow amazing
I haven't watched this video yet but sir ne ye bataya kya ki jab observer na ho to light dusri tarah behave karte hai? Yahi is experiment ki mystery hai
Guru ji Agr aap ka lecture ho na to duniya ke kisi bhi coaching institute ki jarurt nhi ... Fantastic lecture all doubts cleared the most toughest chapter become easiest after seeing this video 100 percent guarantee
There are only few youtubers who are helpful for our career He is among them he is legend of legend . Thank you so much sir for giving us this education.
Sir , pls tell me from where you got this huge knowledge, I am ur biggest fan sir ,I watch ur videos to gain knowledge although I had completed my m.sc physics,really u r doing fantastic job .....
15:42 ..the line he said smilingly is the truth which he had gained from his experience... "After achieving everything u dont have anything..or rather u only have emptyness or nothingness"
1:03:40 A little help guys Upon converting into metre D= 10^-4 m D= 5× 10^-1m lembda= 5×10^-7 m (correct values) In case ur final ans wasn't matching to Sir's, it's 85.6 × 10^-4 after shifting it turns 8.56 × 10^-3 (approx) Thank you Best wishes 💖
Great explanation sir. In love with your lectures. They are addictive. After learning from you, I search for your lectures for each and every topic of 11th and 12th Physics and Chemistry. Thanks a lot!

I have never seen a physics teacher who is so determined to teach...so inclined towards his subject... literally never...Sir is so attached with physics ☺️
I'd like to point one thing, at 1:33:00 Intensity is in terms of cos square phi, therefore the concavity of graph must not change and produce sharp corners at dark fringes, like the graph of cos^2 x. Great lecture though, thank you.
Shivraj Bhosale lmao i don’t watch his free leacture snowflake. I came to his video to show my friend what simps look like. Just go to comment section and you will find finest simps of this planet.

(This man )😎🤏😳how u use these two words for him ?... respect ur teachers.
@@Dr_ooo bhai sorry dil se nikla tha samaj nai aaya kya likhu.Sir ki dil se respect karta hu abhi edit karke hata ta hu.Sorry once again
@@Dr_ooo abey konsa sir cmnts padhte h sahi hi likha tha usne
Brother, i am so thankful to you for all these lectures. Whenever i am unable to grasp some concepts, i know just where to go! Physics wallah! Love From across the border 🇵🇰

Bro jo sir ne 1 ques kia hai uska ans nahi mil raha
Same i always see his lectures 🇵🇰👳
Who else are watching these videos in lock down hit a like for Alakh Pandey sir

Thank you so much sir ....may God bless you with health Nd wealth...(✿^‿^)
I am amazed by Sir's habit of talking like we all are right in front of him. I never feel like I am watching this online. It requires a lot of dedication towards your work to reach this this level of being absorbed in teaching. WE ALL LOVE YOU ALAKH SIR
The most attractive thing which I like in him ...that he is very natural .. specially.❤️❤️ He is not snide.., bogus ... Very energetic always in every lectures
Aap nhi teh toh sir unacademy se kaam chalaraha tah but feel nhi hua ...lkin now im confident wid YDSE thank you sir
May god bless you
Those wu agree sir k liye like tokho
your way of explaining things is so awesome ........it takes no time to grasp any topic ,Hats off for you SIR

Have you noticed sir was full tired....Still he continued the lecture just for us❤️...
He is great ❤️💥
Alakh Sir established a Unicorn Platform.
How?
Simple Answer:- He love Physics. And he can make you Love Physics with super ease.
Love you Sir. ♥️
guys if you are solving the questions by your own self, then you will find a mistake at 1:03:53
the answer will be 0.875mm
True'😀 even I was looking for that in comment sec 😅
I have wasted my last 15 mins trying to solve this, ans wasnt matching, tysm broo
@@mehakkaur6869😎
I just watched double slit experiment experiment on RUclips via animation I Wonder If sir had the proper Apparatus the explanation would be mind-boggling I can't even imagine how amazingly sir had explained this. For those who are unable to get this experiment plz watch the real experiment what it was I am amazed this exp is growing love for physics more n more wow amazing
I haven't watched this video yet but sir ne ye bataya kya ki jab observer na ho to light dusri tarah behave karte hai? Yahi is experiment ki mystery hai
Confidence is on peak after watching ur full lecture😁🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥

1:04:55 I think the answer is .875mm
And second part the ans is 1.25 mm
There are only few youtubers who are helpful for our career
He is among them he is legend of legend .
Thank you so much sir for giving us this education.
Sir , pls tell me from where you got this huge knowledge, I am ur biggest fan sir ,I watch ur videos to gain knowledge although I had completed my m.sc physics,really u r doing fantastic job .....
Obviously from reading books from different source like walter levies sir hc verma other great books of physics
@@vagmine_.vartika ok
15:42 ..the line he said smilingly is the truth which he had gained from his experience...
"After achieving everything u dont have anything..or rather u only have emptyness or nothingness"
Agar koi teacher 30mins padhaye to bacho ke chhodo..wo khid hi thak jata he ..aur app toh 2 hrs akele padha rehe ho...BIG #LEGEND
Edit kari gayi hai video
Sir your way of clearing the concepts of students is the best!!!!!
Hi srija
Lots of Love from Nepal 🇳🇵🇳🇵🇳🇵🇳🇵🇳🇵🇳🇵to the respected sir Alakh pandey🤩🤩💘😘🥰
1:03:40 A little help guys
Upon converting into metre
D= 10^-4 m D= 5× 10^-1m lembda= 5×10^-7 m (correct values)
In case ur final ans wasn't matching to Sir's, it's 85.6 × 10^-4 after shifting it turns 8.56 × 10^-3 (approx)
Thank you

Great explanation sir. In love with your lectures. They are addictive. After learning from you, I search for your lectures for each and every topic of 11th and 12th Physics and Chemistry. Thanks a lot!
Thank you sir u r the best teacher that i ever seen. U make me fall in love with physics😍😍🙈

Who knew that time that this man would create history. ❤️🔥
I have never seen a physics teacher who is so determined to teach...so inclined towards his subject... literally never...Sir is so attached with physics ☺️
School pe speed se padha rehe hai isliye u tube PE ache se padhne ke liye ane walo hum bhi same hai
I'd like to point one thing, at 1:33:00 Intensity is in terms of cos square phi, therefore the concavity of graph must not change and produce sharp corners at dark fringes, like the graph of cos^2 x.
Great lecture though, thank you.
Best teacher in whole world ...lots of love from ur student , ur fan ..🥰🥰
Yah he is the best 😊
