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 mirror is equal to the angle between the reflected ray and the mirror.
The incident ray, reflected ray, and normal are related by the law of reflection, which states that the angle of incidence is equal to the angle of reflection. The incident ray is the incoming ray of light, the reflected ray is the ray of light that bounces off the surface, and the normal is an imaginary line perpendicular to the surface at the point of incidence.
Angle of Incidence = Angle of ReflectionThis is only true if the angle of incidence is greaterthan the critical angle.
The angle of incidence is the angle between the incident ray and the normal (perpendicular line) to the surface the ray is striking.
