      But you think low he just a good teacher who teaches for jee and that's it it is not the best i have heard.
      You know why everyone loves him because we just don't want to open the book and learn by ourselves we totally dependent of spoon feeding he doesn't teach anything outside of book. Then why can't we study from scratch and learn by ourselves I know a young man who cracked iit without coaching without TH-cam went to iit and further mit

    We can solve 2nd question in one more way
    After finding phase difference i.e. (π/3) ,
    We can find 'n' for formula y = { n( lemda ) D } / d
    By ∆x = lemda × phase difference /2π
    Then putting ∆x = n × lemda ( for constrictive interference)
    .°. n × lemda = ( lemda/2π )× π/3
    => n = 1/6
    Now putting 'n' in general equation for constrictive interference
    Y = n × lemda × D /d
    And putting the values of n , D , d and Lemnda
    We will get 'y'

      2. Work on your handwriting (this is actually gamechanger, jitni acchi handwriting utne acche marks).
      3. Paper me sare questions krna. (yep bro even if you know nothing about it kuch to likh hi dena).
