In an experiment for determination of refractive index of glass of a prism by i-delta , plot it was found thata ray incident at angle 35^circ , suffers a deviation of 40^circ and that it emerges at angle 79^circ . In that case which of the following is closest to the maximum possible value of the refractive index?
