Fermat's principle.

Answer 2

Answer:

The required answer is Fermat's principle.

Explanation:

• The angle of incidence and angle of reflection are equal according to the rules of reflection. Be aware that over a rough surface, they could appear to be uneven. On a rough surface, however, it seems unequal because of the shifting surface boundaries. The angle of incidence and angle of reflection are equal at really small surface areas.

• According to Fermat's principle, "light moves between two points via the path that takes the least amount of time, relative to other neighboring paths." The law of reflection, which states that the angle of incidence equals the angle of reflection, and the law of refraction can both be derived from Fermat's concept.

Therefore, angle of incidence =angle of reflection. This rule is explained by Fermat's principle.
