Is this the correct way to measure the angle of refraction/incidence?
Place the object whose refractive index you wish to measure on a clean sheet of paper and draw round it.
Mark out, using dress making pins, a ray of light as it passes through the object by pricking the paper.
Remove object an pins and draw lines to show the path and thereby deduce the path as it passes through the object.
Measure the angle between the ray in the object and outside it using a protractor. I think there are also different ways to do this.. This is for a portfolio! :-)

Google "measure the angle of refraction/incidence".
I already did so, PsyDAG! I browsed, however I wasn't sure what to do so I came here.. Sorry if I sound rude! But thanks for taking time out of your day to help anyway! I apreciate it very much! :-)
