Light can then attain the critical angle of total reflection in the range [beta] [less than or equal to] [[beta].
Refractometer is the more general term since the critical angle of total reflection is a peculiar aspect of reflection, thus all total reflectometers are also refractometers.
With this measurement the critical angle of total reflection is determined with a sighting arrangement (small marks along de).
Firmly attached to the graduated circle is a telescope by means of which the critical angle of total reflection may be observed.
The critical angle of total reflection is observed, through a telescope with crosshairs, as a sharp bright/dark boundary, and its value is read out on a large divided circle.
Here, m is the increase of the angle of total reflection, or critical angle, as compared to natural Ni.
