1-Assertion: A convex mirror is used as a driver's mirror.
Reason: A convex mirror always forms real images

Dear student,

Assertion: A convex mirror is used as a driver's mirror.
This is in fact true and it is used because it forms virtual, erect and diminished images providing a wide area of vision.
Reason: ​​​.A convex mirror always forms real images
This is incorrect.
A convex mirror always forms virtual images because the focal point and centre of curvature are imaginary points and rays after reflection appears to meet behind the mirror.

To conclude, Assertion is correct but reason is incorrect.

Convex mirror are used as rear view mirror in vehicles because the field view of a convex mirror is large and it forms a diminished image so that the vehicles coming from behind can be observed. So, Assertion and Reason are correct, and Reason is the correct explanation of Assertion.
