It does. But when the ray arrives perpendicular to the boundary, the angle of incidence and the angle of refraction are both zero, so its direction doesn't change.
That ray of light is just a radius of the sphere. It's perpendicular to the sphere everywhere, so the angle of incidence is zero ... the ray of light arrives along the normal to the mirror at any point.
The light ray arrives perpendicular to the plane of the mirror.
It is the angle of incidence.
the angle of incidence is the initial ray angle and the angle of reflection is the reflected ray angle
The angle between the incident ray and the normal is known to be angle of incidence The angle between the reflected ray and the normal is said to be angle of reflection By the law, the angle of incidence = angle of reflection
The angle between the incident ray and the normal is known to be angle of incidence The angle between the reflected ray and the normal is said to be angle of reflection By the law, the angle of incidence = angle of reflection
The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.
The angle between the incident ray and the mirror is equal to the angle between the reflected ray and the mirror.
