Plane Mirror Ray Diagram Focal Point. This image is not real but virtual because the image formed behind the mirror by extending the diverging reflected rays backward. On the diagram rays lines with arrows are drawn for the incident ray and the reflected ray.
Before that can be done the focal point must first be defined. Does it tell us something interesting. One useful tool that is frequently used to depict this idea is known as a ray diagram.
Ray diagram uses lines with arrows to represent the incident ray and the reflected ray.
Now that the basics of image formation using a ray diagram in plane mirrors are reviewed practice the following example. Similarly the ray starting from a and travelling towards point c follows the law of reflection. The easiest way to visualize what a image will look like in this type of mirror is a ray diagram. It also helps us trace the direction in which the light travels.
