    Notes for my future reference:
    2:47 d net = 2 theta, direction in which 2nd mirror is from 1st mirror
    3:28 tum velocities me -ve sign lagana bhul jati ho, if opposite
    5:53 m = f/f-u ko use Kara Karo, ache ques bante h idhar se
    6:22 longitudinal m = v²/u² = (f/f-u)²
    6:53 remember the trick ray diagram sir taught in class
    9:17 don't get confused, apparent obj is always formed from ref ray extended backwards, n2= jis med me rays jaaa Rahi hai, N1= jis medium se jaa rahi h
    9:52 this is new, learn
    10:22 four imp remarks
    a) observer and object shud be in same medium
    b) shift is always measured "from" object
    c) + shift means image moved towards the direction of incident ray
    - shift means it moved oppo direction of incident ray
    (Nothing else, related to direction shud be given consideration)
    d) shift doesn't depend on distance of object, or distance btw multiple slabs... S = n_obj ( t1/N1+t2/n2+t3/n3...)
    *Note* d vs i graph, and cutting of mirrors bhi karo
    11:42 R1 woh surface ki rad jise ray pehle strike kare
    12:06 remember - this can be easily derived with power
    13:06 don't forget finally hume mirror milega on combination so further questions mirror ki tarah solve honge
    13:52 this is new, learn
    14:20 optical fibre questions me issue hai tumhe
    16:12 don't forget this is all for thin prism!!!

I want to improve and score 98+ percentile . But I need ur help sir...Plz make one shot videos for physics for first imp chapters and then rest . This one shot videos of ur physics will help me if u will do it for me and my friends. I m prepared with only 6-7 chapters but no physics teacher is able to clear my concepts for jee and how to solve ques. I think if u will make one shot videos for each chapter of physics. It will work for me. Plz sir , help kardijiye sir. Maths and chem ka scene sorted hai mera bas phy hi mera weak hai jiske kaaran mai score nhi kar paa rha hun.... Plz sir bna dijiye ek ek karke saare chapters ki with ques. 🙏🙏🙏🙏 Plz sir.

    Mohit Sir,
    It is because of you that I am able to do many of the Physics chapters properly for my upcoming JEE (Main) examination.
    I hadn't studied Rotational Motion at all earlier. I did it from you and was able to solve most of the questions.
    I was earlier unable to solve many questions of Electrostatics and I was kinda surprised that I completed the entire Electrostatics in just 19 minutes from your channel and thereafter, was able to solve most of the questions.
    I promise you that I'll keep working hard from my side and rock in JEE. It's my dream to be at some great college like IIT or NIT and then, do something big for my country India 🇮🇳
    Thanks alot, Sir
    May Allah bless you and may you always keep prospering and stay happy. Lots of love.
    *Just one question. I am unable to solve the questions of EM Induction, even after studying and understanding the concepts well. Any suggestions ?*

      sometimes if things are still not understood, better skip that one and make strong topics stronger
