What is the principle focus of a concave mirror?
The refleted ray are meeting/intersecting at a point on the principal axis of the mirror.This point is called the principal focus of the concave mirror
When rays parallel to the principal axis of a concave mirror are reflected the pass though?
That passes through the principal focus of the concave mirror
A ray of light traveling parallel to the principal axis of a concave mirror will be reflected out through the mirror's?
focus
Why CONCAVE MIRRORS USED IN TORCH LIGHT?
The concave mirror reflects the bulb's light, and if the bulb is at the mirror's focus, sends it out as a parallel beam.
Where will the image form when you place an object on the principal axis of a concave mirror at a point between focus and centre of curvature?
If the object is placed on the principal axis of a concave mirror at a point between the focus and centre of curvature the image will form beyond the centre of curvature

Where you have to be to see an upright image of yourself in concave mirror?
To see an upright image of yourself in a concave mirror you must be closer than the principal focus. Hope this helps.

If the object is placed on the principal axis of a concave mirror at a point between the focus and centre of curvature the image will form beyond the centre of curvature
Describe the path of the light ray that hits a mirror after passing through its focus?
It is reflected back parallel to the principal axis. (apex)
Will an object inside a principal focus be smaller?
No, for a concave mirror the object will become larger. it is virtual the right way up and it is behind the mirror
What is the principal focus of the concave mirror?
Once you measure it and do the math you will know. Use algebra. Parabolic curves formulas.
Why concave mirror is used for shaving?
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
Why a side mirror is never a concave mirror?
A concave mirror would focus the light back towards the focal point of the mirror. You would not be able to use the mirror effectively with a concave.
