Trust me merre all dosto preboards aren't tough , merra aaj science ka tha preboard aur paper wasn't tough it was soo easy , agar jisne akr sir , ag ma'am aur Amrit sir se phada hoga , for sure all paper which you will be giving will definitely look easiest 😌😌🔥🔥

Your voice is too low!! I have kept my volume very high but still can hear you a bit... Can you in your next video increase the volume..? I hate physics but this video is helping me a lot... Thank you.

Sir
Once check the refractive index topic
n12=n1/n2 is wrong
n12=n2/n1 is correct
Please check please
I'm not discouraging 😃
Ye apne bahut achi bat kahi hai Maine misunderstand kr lia tha muje doubt bhi tha pr apne clear kr dia thank you
Nah man he's right
Cuz only when u compare the speeds of the 2 objects, n12=v2/v1
In case of refractive indices its n1/n2 only
Hope this helps 😁

One of the best series of the channel. Sir please ask all the teacher's to this type of vedio. 😇😇
A mistake done by vedantu is convex mirrior is converge whereas concave is to diverge .
5:14 is given reciporcal information

THANK YOU SIR
Who is Watching before one day of board exam 2024..😂❤️
Sir I am honestly saying you are the best teacher on earth. I hated physics but now it's my favourite subject and all the credit goes to you.
I am 12 student and I was facing difficulty in optics so I decide to start from the start, and the joy of being able to thaught by Abhishek sir is just something. I use to watch him since i was in 9th
4 days left of my science exam. It help a lot
2024 ke boards me Standard incident ray topic hai ya nhi .??..plss anyone tell
Since we know that sin i / sin r = constant . Let the incident ray fall normally on the refracting surface then sin i = sin 0 and sin r = sin 0
And sin0/sin0 = constant
--- 0/0 = constant ( but it is not possible )
Here the second law of refraction fails.
Conceptual understanding apki bohot kam hai
Everyone explaining the chapter in the fastest way they can in 40 mins,20 mins..etc but here our sir is explaining each nook and corner of the particular subject with patience and a deep explanation of basics
Me watching this 7 hours before exams 😭
I know some are telling that increase video quality but this video is 1 year ago and I think sir is good at this type of board but some light effects is needed.
thinking that i would have watched this earlier and scored well in pre boards, but happy that i saw now and now i can score well il boards . thank you sir
❤❤
Hello sir , the spelling of the word vacuum is incorrect in 14:29 . So I kindly request you to correct yourself. It's "vacuum". Thank you
ok genius
Sir I have a doubt in refractive index , what is refractive index of glycerin and which medium . Those who want to know like Karo
Refraction through Glass slab?
i'm here for basics again hehe... just started 12th grade with ray optics :)
do you have any tips for a tenth grader going to write board exams??
When a light travel from one medium to another in different optical densities so, bending of light
Yesterday was my physics exam this helped me a lot, thank you very much sir🙏
Sir I will share this video all video to all my friends and relative so that they also study the chapter in a easy way. Because sharing is caring 😊😊✨✨
