Question

rays of light strike a bumpy road and are reflected. what can be predicted about the reflected rays? they will not follow the law of reflection. each will reflect at the exact same angle of reflection. they will all travel in the same direction. each will reflect at an angle equal to its angle of incidence.

Explanation:

The law of reflection states that the angle of incidence is equal to the angle of reflection. Even for a bumpy road (diffuse reflection), each individual light ray still follows this law. The first option is wrong because all reflections follow the law of reflection. The second option is incorrect as the surface is bumpy, so the normal (for calculating angles) varies at different points, leading to different angles of reflection for different rays. The third option is wrong because due to the varying normals (because of the bumpy surface), the reflected rays will not all travel in the same direction.

Answer:

Each will reflect at an angle equal to its angle of incidence.
