The center of the spherical reflecting surface of the mirror is called the pole of the mirror.
PRINCIPAL AXIS
Some people use concave mirror because when a man stands between the principal focus and pole of a concave mirror,he sees an enlarged,erect and virtual image of his face.this is the reason why a concave mirror of large focal length is used for shaving. concave mirrors concentrate on one focus and while shaving it concentrate on a point and the image is enlarge which prevents the face from cutting. because when a man stands between the pricipal focus and pole of a concave mirror , he sees enlarged ,erect and virtual image of his face .that is why concave mirror of large focal length is used for shaving
The sun rises once each year at the South Pole, and sets once each year. The average number of days in a year without a sunrise at the South Pole is 182.5.
A pole In a circut breaker refers to the number of circuts it controls, single pole only controls one, double controls 2 at same time
180
It is pole.
No such term vertex being used in concave mirror. We would say by the term 'pole' of the mirror. Or optic center of the mirror. Of course vertex is used in case of parabola. Following this we may use vertex synonym to the pole or optic centre of the concave mirror
pole is the geometric center of the reflecting surface.
The geometric centre of a spherical mirror is called its pole. The centre of the hollow sphere for which the mirror is a part, is called the centre of curvature. The line joining the centre of curvature and the pole is the principal axis. A light ray incident on a spherical mirror, after reflection appears to pass through the principal focus in the case of a convex mirror and passes through the focus in the case of concave mirror. The diameter of the spherical mirror gives the measure of its aperture
PRINCIPAL AXIS
The object should be necessarily be placed between the focal point of the concave mirror and the pole of the mirror to produce a larger image(not larger object) behind the concave mirror.
You cant silly! ITS A SECRET!!! Nobody knows the north pole number!
The phone number of the North Pole Branch Library is: 907-488-6101.
the imaginary line passing through the the center of curvature and pole is called the principal axis.
he wrote mirror for me,his number one fan
yes it always produces a virtual image. it is always erect. Its size is always diminshed. Distance from the mirror is always between Focus and Pole
a cold is when your really cold and a cuse is...... your so cold when your looked at the mirror you saw the north pole
