Question

diameter of spherical mirror is 10 cm what will be aperture of mirror​

Answer 1

FINAL ANSWER:-

$aperture = 10 cm$

EXPLANATION:-

The diameter of the reflecting surface of spherical mirror is called its aperture. Mirrors whose aperture is much smaller than its radius of curvature, we use R=2f. as it is given that diameter  2times center of curvature or diameter = aperture

⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔ ⇔

THINGS TO KNOW:-

• In a concave mirror, when the distance of the object is less than the focal length, the magnification will be greater than one. When the distance of the object is greater than the focal length, then the magnification is less than one.

• in concave mirror u and f both are always '-'ve. as they are on the left side of the mirror

• (height of object) is always '+'ve and

• if  is '-'ve means the image is formed bottom of principal axis also image will be real and inverted and if  is '+'ve it means that image is virtual and erect.
