Answer 1

$\huge\tt\colorbox{lime}{AnsweR}$

• The incident ray, the refracted ray and the normal to the interface of two transparent media at the point of incidence, all lie in the same plane.

• The ratio of sine of angle of incidence to the sine of angle of refraction is a constant, for the light of a given color and for the given pair of media.

• An incident ray passing through the normal always goes straight.
