Application of
spherical mirror (Concave mirror) (Spherical mirror means both concave and
convex but you were requested to write about concave mirror only)
i.
In torches and
headlights: The source of light is placed at the focus to obtain a parallel
beam of light.
ii.
In flood lights:
The source of light is placed just beyond the centre of curvature so as to get
intense beam of light.
iii.
Reflecting
mirrors for projector lamps: The object is placed at the centre of curvature to
obtain an image of the same size.
iv.
To collect heat
radiations in solar devices: Heat radiations from the sum coming from infinity
are brought to focus by concave mirror in its focal plane.
v.
Shaving mirror,
dentist’s mirror: It produces an erect virtual and highly magnified image of an
object placed between its pole and focus.
vi. Solar furnaces: Large concave mirrors are used to concentrate
