Question
Answer
A mirror that has the shape of a piece cut out of a spherical surface
Spherical Mirrors
The first mirrors used by humans
Pools of water
Earliest known manufactured mirrors
Polished stoned pieces
The mirrors that the Chinese began making
Silver-mercury amalgams
Conducted various experiments with curved polish iron mirrors
Claudius Ptolemy
The point in the center of the mirror passes through the curve of the mirror and has the same tangent and curvature at that point.
Center of curvature
It's the linear distance between the pole and the center of curvature
Radius of curvature
The imaginary line passes through the optical center and the center of curvature of any lens or a spherical mirror
Principal axis
Midpoint of the spherical mirror
Pole
A point from which the reflection of light actually happens
Aperture
Gives the size of the mirror
Aperture
Also called the focal point
Principal focus
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.
Principal focus
It’s any given point, where light rays parallel to the principal axis, will converge after getting reflected from the mirror.
Focus
types of spherical mirrors
concave mirror and convex mirror
the reflective surface is curved inwards
concave mirror
the reflective surface is curved outwards
convex mirror
the reflected image is magnified but the field of view is limited
concave mirror
depending on the focal length, the reflective image is reduced but the field of view is more
convex mirror
used as shaving mirrors or by dentists and even in telescopes
concave mirror
very useful for drivers as the blind spot are drastically reduced
convex mirror
distance from the vertex to the center of curvature
R or radius
the point where the principal axis meets the reflective surface
Point A
Point lies in the midway between the vertex and the center of curvature
F or the focal point
The distance between the vertex and the focal point of the mirror
f or the focal length
a line passing the center of this sphere which touches the reflecting surface at its center
Principal axis
Rearview mirror
convex mirror
security mirrors in atm
convex mirror
satellite dishes
concave mirror
headlights in car
concave mirror
shaving mirror
concave mirror
