Question
Magnification produced by a rear view mirror fitted in vehicles
Options
is less than one
is more than one
is equal to one
can be more than or less than one depending upon the position of the object in front of it
Solution
is less than one
Explanation -
The mirror fitted in vehicles are convex mirror. The images formed by the convex mirror are virtual, erect and diminished or point size. It shows that the height of image will be always smaller than the height of object. The relation between the height of image and the magnification is, `"m" = "h"_"i"/"h"_"o"`
