Answer: away from the normal.
- A towards the normal
- B along the normal
- C away from the normal
- D perpendicular to the surface
Correct answer: C. away from the normal
Explanation: Going from denser to rarer medium the speed increases, so the ray bends away from the normal (angle of refraction greater than angle of incidence).

Concave mirror ray construction: a ray parallel to the axis reflects through F, and a ray through F reflects parallel, locating the inverted real image. Image: Maxmath12, CC0, via Wikimedia Commons.
