types of spherical mirror and the term related to the spherical mirror
Answers
Terminologies:
There are a few basic terminologies that one needs to know while studying spherical mirrors, and they are:
Center of Curvature
The point in the centre of the mirror that passes through the curve of the mirror and has the same tangent and curvature at that point.
Radius of Curvature
It’s the linear distance between Pole and the Center of curvature.
Principal axis
The imaginary line passing through the optical center and the center of curvature of any lens or a spherical mirror.
Pole
The midpoint of the spherical mirror.
Aperture
An aperture of a mirror or lens is a point from which the reflection of light actually happens. It also gives the size of the mirror.
Principal Focus
Principal Focus can also be called Focal Point. It’s on the axis of a mirror or lens wherein rays of light parallel to the axis converge or appear to converge after reflection or refraction.
Focus
It’s any given point, where light rays parallel to the principal axis, will converge after getting reflected from the mirror.
Types of Spherical Mirrors:
