    I am from Sri Lanka....and watched this because I didn't get what my teacher taught about minimum angle of deviations through a prism....and now I know ..how the graph was made thanks to this video..❤️❤️❤️

    Namste mahesh sir
    I watched both videos
    .But I have one problem.
    Suppose angle i =40 then I want calculate the angle of deviation with formula so how can I calculate with the help formula . What is exactly formula for it? As u given it bit it is so hard to solve it.
    Is there is easy method to solve it.
    I done it but my valve come like this I=30 then deviation angle is 9...
    Plz help

    • @knowledgechannelized5493
      @knowledgechannelized5493 3 роки тому

      You would also need refractive index and the angle of that same prism along the incident angle you have to figure out the deviation with the he showed us for "d"
