Define the principal focus of concave mirror
WebUses of convex mirrors: Drivers use convex mirror as a rear-view mirror in automobiles because of the following two reasons: 1. A convex mirror always forms an erect, virtual and diminished image of an object placed anywhere in front of it. 2. A convex mirror has a wider field of view than a plane mirror of the same size, as shown in Fig. WebThe principal focus of a spherical mirror is a point on the principal axis of the spherical mirror at which, the light rays which are parallel to the principal axis essentially …

WebFocus Definition: For a concave mirror. The rays traveling parallel to the principal axis of a mirror after reflection pass through (converge at) a point F This point F is known as the principal focus of the concave mirror. It is a real point in front of a … WebThe focal point is the point in space at which light incident towards the mirror and traveling parallel to the principal axis will meet after reflection. The diagram at the right depicts this principle. In fact, if some light from the sun were collected by a concave mirror, then it would converge at the focal point.
