# Refractive Index

Classical Mechanics Level pending

In an experiment to find the refractive index of glass of a prism by i-δ plot, it is found that a ray incident at angle $$35^\circ$$ suffers a deviation of $$40^\circ$$ and that it emerges at an angle 79$$^\circ$$. In that case which is the nearest possible value of the refractive index?
