Solution

Concave mirror
Concave mirrors are used as reflectors for flashlights and as headlights for cars. The light source is located at the focal point of the mirror, and after reflection, the rays emitted from the bulb form parallel rays, widening the driver's view.
These rays do not converge because the light source is at the focal point of the concave reflector.
