Refractive index of glass block (Snells law)

17/12/2009 14:22


To verify Snell's law. To find the refractive index of a glass block.


Formula: n = sin i/ sin r.

Errors: Measurement of angles only as accurate a protractor.

Accuracy: If the angle of incidence is made larger then the refracted angle becomes larger, reducing percentage error of the protractor.
