What’s the incident ray?
The ray going toward the mirror.
What’s the reflected ray?
The ray that is reflected off the mirror.
what is the equality in plane mirrors?
object distance=image distance
What does the law of reflection state?
when a ray of light reflects off of a surface, the angle of incidence is equal to the angle of reflection.
a ray of light is incident to a mirror at 30 degrees. what is the angle of reflection?
60 degrees (since the angle of incidence is measured between ray of incidence and normal)
