Answer:

Concave Mirror

Explanation:

Parabolic Concave mirrors with large apertures are used in search lights. In search light, we need an intense parallel beam of light for searching objects. When an object is placed at the focus of a concave mirror, the reflected rays are parallel to each other and also parallel to the principal axis. So, we place a source of light at the focus of the concave mirror.
