Answer:
b) the refracted ray has an angle of 90 degrees
Explanation:
The angle of incidence is measured with respect to the normal separation of the media. The critical angle for total internal reflection occurs is:
Here and
are the refractive index of the mediums. This equation is an application of Snell's law, for the case where the refracted ray has an angle of
