    Happy New Year Sir 😊

    other teachers(without giving a shit about the condition of a child): ye bhi nahi aata, tum to nalle ho, tumse hona nahi, board ki tyaari karlo.
    meanwhile ABJ sir: nahi padha to ab yaad karliya.
    others: Short tricks se answer nikaal lo
    ABJ sir: Abhi humara purpose answer nikalna nahi hai, humne to question se zyada se zyada baaten seekhni hain.
    others: Samajh nahi aya to bas ye formula yaad karlo
    ABJ sir: Mein koshish karunga ki formula na yaad karna pade aur logic se saari baaten samajh aa jayen.
    Love you Team Competishun. Thank you for finding such teachers. For the first time, education doesn't feel like bussiness.

      @sohambhattacharya1159 2 ปีที่แล้ว +2

      Path difference is not consider in incoherent because in incoherent source the angular frequency of the two waves are different and also it varies with time and also the path difference is differ in coherent sources so we can't consider path difference in incoherent sources.

    • @csdoit
      @csdoit 2 ปีที่แล้ว +5

      Kyoki coherent sources me phase diff const hota hain which was in our case phi, so we can directly calculate exact amount of intensity at a point,
      Aur incoherent sources me phase diff time ke sath bahut jaldi vary kr rahi hain (w1-w2) *t isliye hum exact intensity nhi calculate kr sakte hain, isliye humne avg liya hain,
      Hope you understand

      Because if we consider path difference and it is not constant with time then we don't observe interference, ideally we assume it to be either constant or 0. Hope it helps!

      Kyunki vo theta 1 and theta 2 me included h .... trigonometric function ke argument me omega t ke saath milakar hi to phase kehte h ...kyunki source se point ka distance fixed tha and since there is no change in medium ( interference always and always happens within the same medium ) is liye k ya 2π/lambda is fixed ...hence itna constant bar bar likhne se accha hmne ek single constant theta mention kr diya
