If a bus is located at 5 metres from a convex mirror and the image is formed at 2.5 metres at the back of the mirror, then what is the magnification of the mirror?

Correct option is D

The correct answer is (d) 0.5.
Given:
· Object distance from the mirror (u) = 5 meters
· Image distance from the mirror (v) = 2.5 meters (Note: For convex mirrors, the image is virtual and formed behind the mirror, but its distance is positive for this context.)
Magnification formula:
The magnification mmm is given by the formula:
m=
Substituting the values:
m==0.5m
Information Booster:
· Convex Mirror: Always forms a virtual, upright, and diminished image of objects placed in front of it.
· Magnification in Convex Mirrors: The magnification is always less than 1, as convex mirrors reduce the size of the image relative to the object.
· Applications: Convex mirrors are commonly used as rear-view mirrors in vehicles due to their ability to provide a wider field of view.
