Original Khojo Papers practice question — not from a past board paper.
Answer
The incident ray, the refracted ray and the normal at the point of incidence all lie in the same plane. For two given media and light of one colour, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, which is the refractive index of the second medium with respect to the first.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The second law is Snell's law.
