Is convex lens used in car headlight?

What is the difference between concave and convex lens?
A convex lens is thicker at the centre and thinner at the edges. A concave lens is thicker at the edges and thinner at the centre. Due to the converging rays, it is called a converging lens.
Which type of mirror is this?
|Placement of the object||Image obtained|
|Placed at principle focus||Highly enlarged, real and inverted|
|Placed between the principle of focus and the pole||Image is obtained behind the mirror, highly enlarged, virtual and erect|
Which mirror is used in bikes headlights?
Concave mirror is used in headlights of vehicles, because when the bulb of headlight is placed at focus of concave mirror, it allows the light to spread out to infinity (longer distances).
