Nicolas Frank · Answer 1

the reflected light ray is 35° to the normal.

Explanation:

the light ray hitting the reflected surface is the incident ray, and forms an angle of incidence with the normal (the line perpendicular to the reflecting surface). The ray reflected fron the surface is called the reflected ray, and forms an angle of reflection.

since

the angle of incidence=angle of reflection

35° = 35°
