1
Q
What is the law of reflection?
A
when light reflects off a surface, angle of incidence is equal to the angle of reflection.
2
Q
What is the incident ray?
A
a ray of light that comes from a light source and strikes a surface or boundary between materials.
3
Q
What is the normal line?
A
imaginary perpendicular line to the reflecting surface.
4
Q
What is the angle of incidence?
A
angle between the normal line and the incident ray when light reflects off a surface.
5
Q
What is the reflected ray?
A
ray cast back from a surface.
6
Q
What is the angle of reflection?
A
measured between the normal line and the reflected ray.
