Measuring refractive index

Rotate a ray box around a semicircular block, read refraction angles on the protractor, then find the refractive index from a graph of sin i against sin r and check it against the critical angle.

This simulation supports preparation and data-analysis practice. It does not replace carrying out real practical work.
