For driving a car,what type of mirror would you prefer to see the traffic at your back?

Where should an object be placed in front of a concave mirror to obtain an inverted and magnified image?

$A$ light ray incident normally on a plane mirror suffers a deviation of

If the image formed by a mirror for all positions of the object placed in front of it is always erect and diminished,what type of mirror is it? Draw a ray diagram to justify your answer. Where and why do we generally use this type of mirror?

Give one advantage of a spherical reflector over a plane reflector.

$(a)$ Write any three differences between concave and convex mirror.
$(b)$ Draw ray diagram to show what happens to a ray of light after reflection from a convex mirror,if it
$(i)$ is incident parallel to principal axis.
$(ii)$ incident at the pole.
