The north or south most point of the insolations circle of illumination.
The ingoing ray of light is the incident ray
The portion of a light ray that falls on a surface is incident ray.
when a ray box is shown at a mirror it reflectes
it will reflect off it
no!!!!
it is the ray produced when the light ray fall on a medium with angle=90 and this ray produced becomes a tangent to the separating surface.
A tangent
tangent
The north or south most point of the insolations circle of illumination.
The degree of an angle can be determined using the tangent function. From one ray of the angle, draw a perpendicular line until it intersects the other ray of the angle. Measure the length of the first ray (A) and the perpendicular line (B) and set as a ratio of B/A. This ratio is equal to the tangent of the angle.
Reflection off the tangent. Reflection off the normal. Ray Divergence. Interpolation Interference.
I need to look at the drawing in order to answer that question. So do you.
A common tangent is a line which is tangent to two (or more) curves.

The tangent of 0.47 radians is about 0.508. The tangent of 0.47 degrees is about 0.00820.
