Why is a convex mirror used to look under a vehicle during a security check?
a- it forms images that are real, inverted, smaller, and closer
b-it provides a narrow field of view and the images formed are virtual, upright, front back reversed, of same size, and at same distance
c-it provides a wider field of view and the images formed are virtual but smaller and upright
d-it provides a diminished view and the images formed are virtual, upright and bigger
