1.2.1.2 Measure refraction
The extent to which a beam of light is refracted when it enters a medium depends on
these properties:
• Angle at which the light enters the new medium (the angle of incidence)
• Refractive indices of the old and new media
The angle of a refracted light beam through the new medium is its angle of refraction.
