Answer 1

Pascal

Explanation:

Angle of incidence is equal to the angle of reflection. This rule is explained by Pascal.

Answer 2

Answer:

Euclid

The Ancient Greek mathematician Euclid described the law of reflection in about 300 BCE. This states that light travels in straight lines and reflects from a surface at the same angle at which it hit it.

Explanation:

The law of reflection states that the angle of reflection equals the angle of incidence—θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.
