What in the incident ray?
What is the angle of incidence?
The ray that comes out of the laser.
The angle between the incident ray and normal line.
What is the reflected ray?
What is the angle of reflection?
The ray of light that is reflected.
The angle between the normal line and the reflected ray.
What is the normal line?
In the experiment with a laser, mirror and birds eye view.
The normal line is a construction line at 90^0 to the mirror.
We use it to measure the angles.
