Convex Mirrors
Convex:
A convex mirror is a mirror that comes out towards the source of light, like depicted in the diagram. Convex mirrors have many uses, such as the passenger side mirror of a car. In a convex mirror problem, the image created by the light passing through the mirror is always upright, smaller, and virtual.
This diagram shows how the incident ray hits the mirror at an angle that reflects off upwards. The reflected ray reflects off, but the image is still created behind the mirror, which is why the image is virtual. The actual light rays never touch each other.

This picture of a passenger side mirror of a car shows how the convex mirror makes images appear closer than they actually are. The mirror allows the driver to see more of his surroundings, but produces a virtual image, skewing the actual placement of the car.
