Define principle focus of a concave mirror? ​

Answer 1

$QUESTION$

Define principle focus of a concave mirror?

$ANSWER$

Light rays that are parallel to the principal axis of a concave mirror converge at a specific point on its principal axis after reflecting from the mirror. This point is known as the principal focus of the concave mirror.

Answer 2

$\huge\mathfrak\red{☟ \: \: \: answer \: \: \: \: ✎}$

Light rays that are parallel to the principal axis of a concave mirror converge at a specific point on its principal axis after reflecting from the mirror. This point is known as the principal focus of the concave mirror.

ㅤㅤㅤㅤㅤㅤㅤㅤOR

The principle focus of concave mirror is a point on its principle axis to which all the light rays which are parallel and close to the axis, converge after reflection from the mirror.

Uses of convex mirrors:

(1) Convex mirrors are used in rear view mirror in vehicles because the mirror can diverge a of light and create a virtual image.

(2) Convex mirrors are used as reflectors in street lamps to diverge light over a larger area.
