What is a concave mirror ?
A spherical mirror, whose reflecting surface is curved inwards
What is a convex mirror ?
A spherical mirror whose reflecting surface is curved outwards
What is focal length ?
The distance between the pole and the principal focus of a spherical mirror is called the focal length.
What is the aperture ?
The diameter of the reflecting surface of spherical mirror is called its aperture
Position of the object at at infinity
At the focus F, Highly diminished and Real and inverted
Position of the object at beyond C
Between F and C, Diminished and Real and inverted
Position of the object at at C
At C, Same size and Real and inverted
Position of the object at between C and F
Beyond C, Enlarged and Real and inverted
Position of the object at at F
At infinity, Highly enlarged, Real and inverted
Position of the object at between Pole and F
Behind the mirror, Enlarged, Virtual and erect
Convex mirror position of the object at infinity.
At the focus F, Highly diminished, Virtual, erect
behind the mirror and point-sized
Convex mirror position of the object at between infinity and the pole P of the mirror.
Between P and F, Diminished Virtual and erect and behind the mirror
What is [v] ?
The distance of the image from the pole of the mirror is called the image distance (v).
