I didn't really get it in class till I found this particular video.
I have Physics test tomorrow morning and I am lucky to find this video. Thank you sir. Am I the only one benefiting from this video??
No here me too
Anyone for 2025 board
😛
It is gift for us
Welp I'll be writing that
Navodaya fans like karo
@@akhil8458 I am also navodayan
You guys started studying when I was in class 10th I was enjoying my holidays
No Online Tution,No Offline Tution Because,Manocha academy is there 🔥🔥
Yes
🥰
My parents won't understand this 😅
@@shadoweyguy3 just ask them they will buy it happen to.me also I thought I was going your get a job at 13 for this 😂 but I asked.my parents they bought it without any hesitation
@@shadoweyguy3I bought this course last year honestly it isn't worth it all their good videos are for free on yt their app just consists of 5 hour lectures and u don't even get perfect by that time cuz today generation attention apan edit - I just think I did not have much appreciation towards study and only bothered to watch videos that that pretends to be friendly but his yt vids are enough for exams and some effort from you
He made me understand sign convention in a shot, inplace of going tution🎒 and school 🏫I didn't understand it that well. Thanks a lot sir❤
0:08 Image will form *Between C And F* .
Any one started preparation for 2024-25 board exams
yep i did
Yes I started to 12 class board exam
Can't describe the "explanation" what you do in every video with the brilliant use of animations, i just wanna say thank you so much...! Sir
sir on 7:16 i think the image should be inverted becuz magnification will be -2 and if m is - it means the image formed should be Real and Inverted
Ya
The object is real and inverted . Now if sir took a line that is in the direction of the object it doesn't mean that the image formed is also erect . That line can certainly be extended right?
Ur Right. He has done a mistake!
There is no such type of mistake that you think. Listen carefully sir had said that the object and image height are positive because they are along the Y - axis not Y' - axis. So along the Y - axis the sign is gonna to be +ve.
@ashifraza434 Real image is always inverted brother
SIR YOUR TEACHING IS JUST AMAZING; KING 👑 OF ALL SUBJECTS ......
Yes 💯
This is the chapter that I'm still planning to ask for second teaching from my physics teacher because I were absent when he taught this but finally I don't need anymore thank you sir❤️
was** not were🙂
@@deepak0148 my English is bad bro don't mind at least y'all understand the meaning right?
Savage😜😜
He is the best teacher i have ever seen in my life
thx a lot for saving my life coz I have exam tomorrow and I wasn't able to understand this concept until your video was dropped here
Great to hear that it's helpful. All the best for your exam!
Me too😂
Me tooo
Hats off to the explanation of this guy

*Properties of the image* - Diminished, Real and Inverted.
Best video that i have ever seen. May God bestow His mercy upon you.
Sir for example of mirror formula the image is formed below the principle axis as it is -30 cm. Please check sir.
2026 10th batch, It is anew teacher can't understand anything this video is very helpful.Thank you very much.🙏🙏🙏
awesome teaching, I'm learning from these videos to understand my Child's progress :)
2024-25 batch attendance here
Very well explained.The way you explain with the picture and images is mesmerising.Easy to understand!Ty sir.
Hello Sir, In the example b/w 05:40 to 07:20, You have obtained the image upright whereas if we apply the rules of ray diagram the image should have been inverted. Kindly elaborate.
Exactly
just a small mistake... it should be real and inverted. But image distance stays the same
Most helpful
Sir I have a doubt what is the difference between a mirror and a lens and difference between sign convention of mirror and lens
He should review this.
the concept is exactly crystal clear
Anyone for 2024 board exam?
iam😅
Me😊
Me
Tommorow exam and I am here to study this
Me
i am from ethiopia and you are unique teacher thank you for all
Glad to hear that
me too your videos are helpful
Sir you literally cleared all my doubts,You are such a fantastic teacher. ❤
Your explanation is a top notch 🎉
Shobit nirwan is god of maths
Nice lecture sir, thank you soo much 💖
7:16 Sir isn't the image supposed to be inverted because it is a concave mirror and the object is between C & F ?
Yes I agree
Thanks a lot sir... your hard work and perfect explanation really God gift....u r really guru of whole student and their parents..... hearty wishes u to good health and prosperity.,.tq so much sir
Most welcome
So easy with your superb explanation 🖇️💕
Simple language easy to understand 🎀👀
any bro watching a day before exam?
Me lol 😂
😂 me also
This video is literally amazing. Teaching was simple ,understandable and over all awesome ❤❤
Sir,
In this video 📸 the image should be inverted in first example (problem)
8:36 sir when the object is placed at focus the image should form at Infinity and it should be real and inverted. So, the image length should be negative
Sir can you teach how to solve numerical related to magnification and mirror formula
Sir (7:13 )why the real image is not drawn inverted @30 cm using concave mirror.
Sir is different than others
Sir make it videos up to jee level it will very helpful for us...🙏🙏
Sir, at 13:46 shouldn't we take -v/u as -(-18)/-9
Which makes it +18/-9
The minus in 9 will be cancelled with the minus on (-18)
I am a Lengend because I have exam in 1 hour 😂😂
First time i understood this concept. Very helpfull🎉🎉🎉🎉🎉❤
Why there negative sign to image distance in the formula of magnification
Thanks a lot sir ❤❤❤
Really good. His intention is that we understand.
7:20 sir real images are always inverted but why it is not inverted
Sir can you upload a vedio like this about lens equation
Excellent sir very nice explanation even our teachers are not said thus like sir very Excellent 😊😊😊
7:12 image should be inverted!!
In the first question. Placing the object in between c and f. How can we know the object falls into that range.? Why is it 9cm didn't fall at C.? Maybe that does not disrupt us from getting the answer. Does it?
Secondly
Does it mean that image height must be positive for both convex and concave? I ask this because, I understood it after an images is formed but I can't figure it out when a mathematical question is ask until I solved it. So. How do you know that the image height is positive or negative? For example , an object of size 1cm, how did you actually know that this object is having a positive sign.? Thank you for the teaching.
Dear Sir
I stay in a small city not in a metro.
Can you kindly suggest some good reference books please.
Your videos are so helpful
I humbly thank you
Vidya
I am not the teacher, but I suggest you use Lakhmir Singh, it helped me :)
Go for Cengage for best results
oswaal
In my book the lens formula is 1/v - 1/u =1/f but in the video its 1/v + 1/u =1/f???????
1/v+1/u=1/f is the mirror formula 🙂
Real image is inverted.
Thanks sir good explanation
Thanks 😊
الله ينور عليك بجد
Anna nuvu toppu anna 🎉🎉
Ma sir kana baga chepav😮❤❤
Wow! Excellent explanation sir!!
It helped me a lot in my exams thank you😄😄
Please make a video of mutual induction
Thats excellent Sir. Kudos to your teaching skills.
Upload video on regular basis on different topic of class 10
Legends watching this before a day of exam
dcual
After seeing your video I am ready for 2marrow exam👍💯
Sir but in our book lens formula is 1/f=1/v -1/u 10th std science book
What is the difference between pole and origin (O) in sign convention?
If we take concave mirror as left half piece then how the sign conversion please explain it sir
sir, you are great in science explanation
Super explain thanku sir
Sir you teach very well😄😄😄😄😄😄✌💯💯💯💯💯❤
Thanks
Any one of class 12 😂
Here for 8th class
Me🙌😂
Sir please bring sign convention for spherical lenses and electricity
Sir doubt pls give steps to find magnification, v and etc I get confused sir what to do next ..
Sir , at 8:37 the ray diagram for object played at focus is not correct. The image is formed at infinity.
in minutes 16.58,why the sign of f is positive?isn't the sign of f is negative for convex mirror?
two mistakes so far...
1. Concave mirror, the image is inverted for the first example, not upright.
2. Concave mirror, when object is at focal point, image is infinite (infinity)
caught this too...i love this guy and although these mistakes are pretty costly for many, he isn't consistent in making them. in his other videos he clearly states the correct occurrences. something must've been wrong in his algebra.
Thank you soooooooooooo muchhhhhhhh ❤❤❤❤❤❤. Literally got full 26/26 in physics. I am really obliged and grateful to you
Congratulations
Who the fu*k keeps the test for 26....??
@@hello4787 our school has science test out of 80 total. So 26 for physics and biology and 28 for chemistry
@@hello4787why the f*** do u care
@@hello4787😂😂😂
Pretty explanation sir
Thankyou for this wonderful class..it helped me a lot!!❤
Can you please tell about tenth class structure of atom sir
Really elegant 😊😊
Ummm sir isn’t the mirror formula 1/v - 1/u = 1/f ???
Sir ji aapki shakal aur Figure bilkul mere chacha ji se milti hai. Sir ji sahi keh raha hun ki aapke jaisa to mujhe kabhi mere school wale Teachers ne bhi nahin padaya . Thank you 😊 so much ❤️👍🙏🙏
Thank you sir
Welcome
Sir plzz upload the electromagnetism vedio🙏
7:22 it should be a inverted image?
simple and best. thanks
Is 1st practice question answer is 18cm
All my dates are cleared now 😊
THANK YOU 👍
Not a dates that is doubt
Tq sir for explaining ray diagrams
Your teaching was nice and great understanding 😁👍
Sir really you are best from 8 th to 9 th i hate physics I thought it is boring but when I am listening your explanation for me physics became my favorite subject tq sir❤❤❤❤❤
Very clearly explained
At 16:55 shouldn’t the focal length be 2/15 and not 1/15?
Outstanding explanation ex
Sir , I have a suggestion. Please explain the sums also , so that we don't get confused or any calculation mistake will occur
BTW I like your way of teachingg😊
At 07:20
I have a big question there since the image is real how it takes negative instead of positive as well as focal length must br positive.
So what is wrong?
Bro sign convention
