What is principal axis in hyperbola?
The principal axis of a hyperbola is the straight line joining its two foci.
Why are the diagonals of a rectangle not axis of symmetry?
Because they don't create a perfect 'mirror image' of each other
Is the reflection of a figure in the x-axis equivalent to the rotation of that same figure 180 about the orgin?
It can be but in general a reflection in a line produces a 'mirror image'
What is intercept in a graph?
Wherever a given function crosses either the x-axis (which would be an x-axis intercept), or where the given function crosses the y-axis (which would be a y-axis intercept). Functions sometimes have more than one intercept of either axis, so be careful to check for those.
What is the rule for a reflection across the x-axis?
For a reflection across the x axis, both the slope and the y intercept would have the same magnitude but the opposite sign.
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
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)
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
A ray of light traveling parallel to the principal axis of a concave mirror will be reflected out through the mirror's?
focus
Rays traveling parallel to the principal axis of a concave mirror will reflect out through the mirror's focus.?
true
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
Can chord is used to find the direction of reflected ray on a concave mirror if rays are parallel to principal axis?
no
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.
Are rays perpendicular to the principal axis of a concave mirror converge at or near the focal point?
It should be parallel. Rays "parallel to the principle axis of a concave mirror converage at or near the focal point.
A ray of light traveling parallel to the principal axis of a concave mirror will be reflected out through the mirrors?
If the light approaches the mirror along the normal (perpendicular to the mirror), then it reflectsback in the same direction from which it came.In that event, the angle of reflection is still equal to the angle of incidence . . . they're both zero.
What is principal axis of a mirror?
the imaginary line passing through the the center of curvature and pole is called the principal axis.
Which light rays striking a concave mirror are reflected so that they pass through they focal point?
Rays which are parallel to the axis of the concave mirror will converge to the focal point.
