    Sir i am student of class 11 and whenever i got totally confused in any topic during studying physics i watch you vedieos .
    I must say your are one of the best teacher who not only teach us us orally but also with the help of pictures you help to understand us practically
    Also jo derivation meri book ma bahut lamba choda diya hota hai voh aap chhote me hi bahut acche se samjha deta hai .thankyou so much sir

    Sir it is true for total radiation or for monochromatic radiation

  • @pselv11
    @pselv11 3 роки тому

    I don’t understand Sir why u put the unit area in the end when area was cancelled out. Shouldn’t it be just rate of radiation?

    • @knowledge5943
      @knowledge5943 2 роки тому

      Remember that to cancel both the areas they must be equal. So the area of the black body and the substance must be same. So if you don't want to put unit area then you have to mention that black body and the substance have same area.

    Waiting for a fast reply,thanks

    • @edupoint.physics
      @edupoint.physics  6 років тому +1

      +Sunny Singh
      Good.
      Agar koi sirf absorb hi karega to usme stored energy badhte hi jayega. Hamesha ke liye kya ye possible hai?
      Khud vichaar karein.

  • @yuptkhan864
    @yuptkhan864 6 років тому +1

    Sir according to you some radiation will transfer from cold body to hot but according to claussius law of thermodynamics heat can never flow from cold to hot and we know that heat is a form of radiation?

    • @edupoint.physics
      @edupoint.physics  6 років тому +1

      Hats off to classical mechanics.
      What you are talking about is a macroscopic view.
      I think you need to watch the video carefully keeping your prejudices aside.

    • @yuptkhan864
      @yuptkhan864 6 років тому +1

      EduPoint I watched it and like your explanation sir but you are wrong at this point because whether it a macroscopic or microscopic it's a damn law it cannot be disproved without an explanation of proof 😊💓
