What Mirror Used In Search Light. Assertion :the mirrors used in search lights are parabolic and not concave spherical. Alphonse mangin of the french army invented a double spherical glass mirror that was widely employed in searchlights until about 1885, when the parabolic reflector came into use. A searchlight (or spotlight) is an apparatus that combines an extremely bright source (traditionally a carbon arc lamp) with a. In a concave spherical mirror the image formed is. Parabolic concave mirrors with large apertures are used in search lights. For military use, the reflector is generally metal. A reflective mirror forms an integral part of the search light's design by focusing and directing the emitted light into a. Hence, it is also called a. A convex mirror is a curved mirror that forms a part of a sphere and designed in such a way that light falling on its shiny surface diverges upon reflection. Concave mirrors are used in search lights and torches so that we have a more focused light beam which will not diverge out and hence help. In search light, we need an intense parallel beam of light.
