The angle at which the incoming light ray strikes the reflective surface is also known as?

Explanation:
That angle is called the angle of incidence. It’s measured between the incoming ray and the normal to the surface at the point where the ray hits. For a smooth reflective surface, the law of reflection states that the angle of incidence equals the angle of reflection. The angle of refraction would apply if the light passed into a different medium and bent, which isn’t the case with plain reflection. The apex angle is just a geometric term and isn’t about how light interacts with a surface.
