    Energy is dependent upon wavelength we say that shorter the wavelength more energetic will be the wave but how it is possible that the waves of primary and secondary have same speed wavelength and frequency as they have different energy according to Max Plancks Frequency is directly proportionally to Energy ??

    • @nancydutt4824
      @nancydutt4824 6 ปีที่แล้ว +1

      Samarth Mathur backward wavefronts are rejected bcoz the amplitude of secondary wavelet is proportional to 1/2(1+cos@)and for backward wavelet @=180° and (1+cos@) is 0

    Sir..i have a little confusion if light is an electromagnetic wave then,why it gets slow while going into denser medium to rarer....if we are using wave theory i think...i know it would be wrong but, sir...think once...!!
    Why it gets slow if it is electromagnetic wave.....!!

    sir in this u have expalined both reflection and refraction
    then why u have made wavefronts outside the mirror at point A in reflection
    and wavefronts inside the refraction 😮😅😅
    both mst pdate hoo sir ...mai to fan ho gyi

      A request from all my friends,
      1. Could u please arrange for english lectures since students from south india like me are greatly affected.
      2.Could u please arrange for pdf of the important points which u discuss which we can be readily revised during the last minutes before our exams.
