Name the type of mirror used in the following situations:
a) Headlights of car
b) Solar furnaces
a) Headlights of car: Type of mirror used is concave as the light of lamp undergoes divergence from reflector surface and cover large area in the front.
b) Solar/rear view of vehicle: It is a convex mirror as it gives diminished, virtual and an erect image of the side or rear with wider field of view. A convex mirror enables driver to view much larger area than would be possible with a plane mirror.
c) Solar Furnace: It is a concave mirror. As sun rays after reflection from its surface, get converged at focus with much intense heat.
