2024-2025 batch 🙋‍♀️

20223-24 batch 🙋

English aur hindi ke transition me sir ka tone kitna badal jaata hai!😂

Rare to find teacher like you, who makes physics so simple to understand

best explained ever...!

2:28😂😂😂😂love you sir from North east

Please dont disrespect your teacher.....he is teaching for us... He could have taught cbse ...but he chose icse only bcoz of us........atleast he is teaching....and that totally free of cosst.......may u live long sir.....do ur best and LET THE DOGS BARK BCOZ HATERZ GONNA HATE...

When I saw your videos, and came to your channel to subscribe, first thing i checked was whether or not you are consistent in putting up videos till date or not? Have seen many experts start a channel and leave it midway. Please keep posting. You are more than awesome and a hope for physics learners. God bless you with the energy to pursue this passion.

U are just like my friend who teaches everything before 15 mins of my exam

This is white magic How can you teach so good???😃😃😃 I can certainly tell you practise teacher sorcery.

A day before physics board exam ..... I don't know lens maker formula at all..... I said to myself " darna kyon hai physicswallah hai na """ thank you sir ....greatly indebted to you

2:28 sir ne Hindi bol hi di🤣🤣🤣🤣

Don't stop making ur spectacular videos...I always get massive help from your videos..that way you teach......clears the doubts inside my mind!!!!! .......You generally teach all ICSE chapters in Physics and I would like it if you complete the syllabus really fast but there's no hurry!!!! I never loved reading or learning from a phone but now you seemed to change the aspects even.....I am obliged to call you a sir!

Batch 2023-24 attendence lagao ❤

Tomorrow is my phy boards exam...any one like me???😂🥺💔

I know if you are watching 👀 this video now then I can tell that tomorrow is your physics exam, because that's what I am doing now watching his video now before my exam 😁😁 So, chalo dekhte hai feer ha ki kal ka paper kesa jata hai

You have became my only hope when I just determined that I will study science in most interesting and efficient way instead of learning and memorizing topics as I always used to do.

Sir. Whatever be your way of teaching, you're truly an inspiration. You teach so so so well, sir. Keep doing this, sir. Thank you so much sir.

U covered 1 exercise in 10 mins truly appreciate your help.

Thank you so much! This helped me a lot in my physics exam

A god in teacher's face

Thank you sir !! finally understood how we get object distance in negative !! 🙏🙏

wow amazing teaching skills. obviously one of the best teachers on youtube. best explained ever..

😊Thanks sir for being here for us... your work is appreciable😊☺...

2:28 sir ki hindi bhi nikal hi hyi😂😂😂😂😂😂😂

2 hrs before board ✨️

Us time me aur aaj me aap bht change ho chuke hai🔥🔥

Excellent way of explaining sir. Great job!!

You are the best teacher You always clear all the concept in the first time I don't need to repeat and repeat the video for concept clearing Thank you sir God bless you

1 night before present

Tomorrow is my physics board and now I have started to study 😅

Love to watch your videos. Btw i m a mathematician but due to TET exam i hv to summarise all the things of physics what i hd learn... N then i search on youtube n then gt ur tutorial.. Like it bro...

Thank you sir, you cleared all my doubts on sign convention

Legend watch one day before board exam 😂

2024--2025 Batch🤚🤚

I'm watching this before my exam sir We don't get enough for preparation and you are my only hope Thank you so much ❤️❤️

Keep up with the good work. Your videos are really very helpful

After seeing your video lens numericals are crystal clear sir😀... Great Job sir👍🙏

I forgot that's English version of our Alakh sir. Looking slim & more handsome sir.😆

Best teacher ever I seen

One of the best teacher who has the urge in him to make students better. He could have easily taught in vedantu or unacademy like online institutes but he chose to put up his own channel.... Hope the channel grows day by day... Loads of love and wishes... ~SAMADRITO Student of Adamas International School,Kolkata.

Your teaching is awesome sir😊

Sir please tell me that why we take 1/f,1/V and 1/u? why we take one above the spherical mirror or lens terms? If we not take one then what problem will create..????

You are such a great teacher. Thank you so much.

U r great sir... U clear all my doubts.. Thank you sir...

Sir if mirror is not given in question so ,which sign i put in v,u,m and f ..can you plz tell me sir , shubham

Wow what an wonderful explanation it was. Thanks a lot Sir.🙏🙏🧠🧠

Your all videos are learnable. I have learnt this chapter from three teachers and the result was confusion in image formation of spherical mirrors and lenses but your videos cleared everything thanks for uploading the whole series but plz try to explain in hindi because its makes the leaning more comfortable and interesting nhi to pura lecture boring ban jata hai

can someone tell when is the image distance i.e v in convex lens positive or negative?

i am so thankful to you sir . I have watched many videos about sign conventions but i did not understand. But now I understood . Thanks a lot sir..........

i subscribed u when u were having 1k but now very happy to see your 200+k subscriber

@physicswala i m confused...we say that that a slanting line coming goes straight from the lense but the example you gave the slanting line went slanting and not straight??? how can this be possible????please hurry tell sir!!!!!

2024-2025 batch 👉👉

All doubts and confusion clear sir from this video thank you so much sir👍👍👍👍👍👍👍

Sir you are the awesome teacher i ever met....or may met in future ....sir you have the most different style of teaching...thank you sir for putting soo much efforts for making these videos and helping us...thanks a lot sir🙂🙂

Best teacher for every student😄😄

2023 student anyone !?

Tomorrow is my boards 2024 batch 🙌🏻

8:23 Isko mind me karne k liye 1 trick hai F1=10cm diya hai iska matlab 2F1=20cm hoga aur object bhi 20cm diya hai matlab object is at 2F1 so image will be formed at 2F2 jus opposite and at same distance.... Ty to ALAKH SIR for te best explaination

From Physics Wala to Physics Wallah, sir we are with you And will always be thankful to you for your full-hearted effort 😊😊

No body in this whole universe can teach like Physics wallah sir.🙏🙏 Your amazing explanation is the universal truth of physics, made easy.

Sir please tell me the solution of this numerical At what position a candle of length 3 cm be placed in front of a convex lense so that it's image of length 6 cm be obtained on a screen placed at distance 30 cm behind the lense? What is the focal length of lense?

Sir ,very well doing a great job Fabulous never see a teacher like you

Beat explanation sir , it's amazing sir you make theory crystal clear like diamond, salute you sir, hats off sir for your explanation

We'll congratulations sir on your achievement sir thank you

Thank you for clearing my doubt

Thankyou for clearing my doubt 🙏🏻

Sir please do make a video explaining about magnifying class and application of lenses.. Ur lessons r very helpful!

SUPER DUPER LECTURE I LOVE IT THANK U SIR.

Tommorow is my physics boards 😂 and im watching 4 hours before exam

Thankyou sir mujhe to kuch samajh hi nhi aa raha tha pehle lekin aapne samjhaya to sab kuch aa gaya...thankyou so much...

Sir,please upload ICSE calorimetry numericals. Plz plz plz.........…....…

Who knew that this man will own 1.2B $ ed tech company today!

Thanku sooo much sir for every topic of each and every chapter of class 10 icse ...I m really grateful for u to have u as my physics teacher ..due to ur efforts in ur videos my physics exam went really very well ..thank u so much sir ❤️ ..PW is always an emotion ❤️

Is it possible that image can be formed right/left instead of erect and inverted in any situation by any mirror, Any how !

Maine video mirror se lens ka bdla aur sir ne to India ko usa se bdl Diya...😂 Btw nice explanation as always

I think this is the shortest lecture of Alakh sir for phyics lecture 😀😀😀

CGL aspirant is here in this channel. Thanks bhai to clear my concepts. I was really getting confused about the sign conventions.

Sir APK lecture bhut hi ache hote h ...easily smjh me aa jati h ...tnx sr

Class x icse board students to PHYSICS WALLAH ..tum jo aaye jindagi me baat bn gyi♥️

Well Explained

Sir in concave or convex lens so where v is image (positive or negative

Very excellent explanation.......we loved it

East or West,,Physics Wallah is the best 👌 👍 😍

Loved ur teaching Sir... I'm very happy..

sir in 10 minutes video u gave us a lot of knowledge

We all may have new facilities to study, new teachers with smart boards and all.. But still all we do is to come and understand the concepts from these old and nostalgic lectures.. ❤

Sir,you are better than all

Thanks very helpful for me

Best explanation I have ever seen

Best explanation especially about this topic sir.. Thanku

A blessing for students like me ❤️

Sir maine aapka light chapter full 1 hour wala dekha tha ... earlier I thought that this ch was very difficult ... but after watching the whole video vo ch mere liye halwa ho gaya ... Image formation toa halwa ka bhi halwa ho gaya ... Your explanation and way of teaching is very amazing all over KZfaq. 🔥🔥🔥🔥🙏🙏🙏🙏🙏🙏🇮🇳

Today is my physics boards 💀

Thank u sir ,way of explanation is very good.

2024 batch hey🙂😂

6 yr ago🥲🤌 When i was in 7th class🥺

Yar! Thank you so much sir! I was confused in magnification part in lens and if I hadn’t seen this video I would have refer my class work and I have written ulta pulta! Thank god I found mistake and corrected it! I can’t thank you enough. Last exam I got 15/16 because of you and intact I bunked my school for whole month so teacher was impressed of me! Thank you again, tommrow I have again exam. Wish me good luck.

Thanks sir for help me es lockdown me aap hi hamaare physics ke teacher h
