Answer:
1. The incident ray, refracted ray, and the normal lie on the same plane.
2. According to Snell’s law of refraction, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.

1. The incident ray, refracted ray, and the normal lie on the same plane.
2. According to Snell’s law of refraction, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant.
