This is the kind of knowledge that we would like to obtain from the ray diagram. The qualities of this image will probably be discussed in additional element in the next section of Lesson four.

Considering that the graphic length is unfavorable, this means the picture is behind the mirror which is virtual. The impression will likely be upright.

Angle: Regulate the mirror’s angle to capture the specified viewing region, guaranteeing a comprehensive check out of oncoming targeted traffic and probable hazards.

Rays from a standard position on the article are reflected in this kind of method that they appear to be coming from at the rear of the mirror, this means that the impression is Digital and can't be projected.
