In what cases is the angle of incidence of a ray of light on the border of two media equal to the angle of refraction?
| March 14, 2021 | education
This situation occurs in three cases.
1. Only when the data of refraction in two media are identical, that is, they are the same.
2. When the incident is perpendicular to the interface itself.
3. And then only when the refractive indices in the two media are identical and are the same: the incident beam is perpendicular to the very interface between the media.
