reflection Flashcards
what are the two types of reflection
specular and diffuse
what is a specular reflection
reflection off smooth surface
what is a diffuse reflection
a reflection of a full or irregular surface
what are the two laws of reflection
1) the angle of incidence and angle of reflection are equal
2) the incident ray, reflected ray, and normal lie on the same plane
what is reflection
the bouncing back of light from any surface
what is an incident ray
the original incoming ray
what is the reflected ray
the ray that bounces of a reflective surface
what is the normal
the perpendicular line to a mirror surface
what is the angle of incidence
the angle between the incident ray and the normal
what is the angle of reflection
the angle between the reflected ray and normal
