The positions of the source of light with respect to a concave mirror
Explanation:
Two types of spherical mirrors:
--Convex Mirror
--Concave Mirror
The fundamental contrast between a convex and concave mirror lies in the picture framed by the two mirrors, for example while convex mirror structures lessened picture, the concave mirror either frames a broadened picture or a reduced one, contingent on the situation of the object.
Torch light
It is positioned at the focus of the concave mirror, F.
Projector lamp
It is positioned at the centre of curvature,C.
Flood light
It is put beyond the centre of curvature.
