Question

Formula in terms of angle of prism to find refractive index of liquid

Answer 1

The formula for the refractive index of a prism is:

μ=sin(A+Dm2)sin(A/2)

However, this requires me to find out the angle of minimum deviation (Dm). This would require me to take several readings, plot a graph, and then find the minimum point of the graph.

If I have two readings of the angle of emergence and angle of incidence, is there a way I can find the refractive index of the prism?
