    NA is defined as the sine of half the angle of acceptance cone, thats very
    true but in the video above the definition it says NA=sin (phi) that is
    sine of acceptance cone….. or is half present and m not able to
    c………..

    here phi and acceptance angle are not same>>>phi is the maximum angle made
    made with the fibre axis which apparently is equal to 1/2 of acceptance
    angle
