The reference line is the normal (perpendicular) to the surface.
A reference line is a line that is perpendicular to the surface at the point of incidence. It is used as a point of reference for measuring the angles of incidence and reflection relative to the surface. The angle of incidence is measured between the incident ray and the reference line, while the angle of reflection is measured between the reflected ray and the reference line.
The angles of incidence and reflection are equal when light reflects off a smooth surface. This relationship is described by the law of reflection, where the angle of incidence is the same as the angle of reflection.
No, the angles of incidence and reflection are always equal when a light ray hits a surface and bounces off. This is known as the law of reflection.
The angle of incidence and the angle of reflection are related in the sense that the two angles are always the same. They are always equal.
The angle of incidence and reflection are reference to of a line normal or perpendicular to a surface. The incidence angle is the incoming ray angle relative to the normal line and the reflection is the outgoing angle relative to the normal line. Both angles are in the plane containing the normal line and the incidence ray.
When talking about reflection (normally with light), one works out the angle of incidence and the angle of reflection by drawing a line that is perpendicular (90 degrees) to the reflector and measuring the angle between this line and the ray of incidence/reflection. This line is called the normal line. It is easier to measure the angles of incidence and reflection on a flat surface, because it is easier to draw an accurate normal line.
They are the angles made by the incident ray and the reflected ray with the line perpendicular to the reflecting surface at the point of reflection.
Not usually. (Only when the angle is 45 degrees.)"The angle of incidence is equal to the angle of reflection."
The angle of incidence and the angle of reflection are related in the sense that the two angles are always the same. They are always equal.
You apply the law of reflection. The angle of incidence is equal to the angle of reflection. The angles are measured between the rays and the normal at the point of incidence, which means the line at right angles to the surface at that point.
No, if the mirror is flat (a plane), the angle of incidence always equals the angle of reflection.
The angle of incidence is equal to the angle of reflection.
