Is it possible to find refractive index from diffraction?

  • #1

Homework Statement


I am trying to find the refractive index nylon (fishing line) , however when I used a laser onto the fishing line (nylon) it looked like it diffracted.

Homework Equations


I am able to find the diffraction if that was what it was showing, however I dont know how to calculate after that.

Nice shots ! Hello JPL, :welcome:

As an experimentalist, I would compare the patterns you obtained with
  1. the pattern you get from a steel wire (or otherwise opaque wire) with same thickness
  2. the pattern you get with a slit as wide as the wire is thick
