Field of View of a Mirror

 

Field of View of a mirror :- The field of view of a mirror refers to the extent of the surrounding environment that can be viewed through the mirror. It is the region where diverging rays from an object or an image are present. We can see an object or image only if our eyes are present in the field of view. Field of view is decided by the light rays which gets reflected(or refracted) from the extreme ends of the mirror(or lens) and depends on the location of the object in front of mirror(or lens).

 

The field of view of a mirror depends on its shape, size, and curvature. It has been observed that a convex mirror gives a wider field of view than a flat mirror, as it can reflect light from a wider range of angles. Therefore, convex mirrors are used as a rear view mirrors in vehicles. The size of the mirror also affects its field of view, with larger mirrors typically having a wider field of view.
