What is the ray of light traveling parallel to the principal axis of a concave mirror that will be reflected out through the mirror?
A ray of light traveling parallel to the principal axis of a concave mirror will be reflected through the focal point of the mirror after reflection.
Which light rays striking a concave mirror are reflected so that they pass through the focal point?
The tendency in case of concave lens would be diverging one. When parallel rays fall one side of the concave lens then due to divergence they appear to come, note down that "they appear to come" from a point on the same side. And this point is named as the virtual focus of the concave lens. Now as a ray passes through this virtual focal point that will be definitely a diverging one. Now due to diverging action of the lens, that ray will be further diverged and that will appear to come from a virtual point on the same side and some what nearer to the concave lens. Hence the image will be virtual and diminished and erect one.
Why concave lens form diverging rays?
If a ray of light enters a transparent object like water or glass at an angle the path of the ray is deflected. When it emerges, it's deflected again, but in the opposite direction if the ingoing plane and the outgoing plane are parallel to one another. This effect is known as refraction. When a parallel ray hits a convex lens this refraction causes it to emerge as a non-parallel ray and there will be a point at which the ray becomes very narrow - maybe showing as a spot of light. This is the point of focus. If the lens is concave, the effect is reversed and the ray emerges as a steadily expanding ray.
What direction does a focal ray from an object proceed after passing through a diverging lens?
After passing through a diverging lens, a focal ray will diverge away from the principal axis of the lens.
What is the point on a concave mirror optical axis through which every light ray that travels parallel to the optical axis toward the mirror moves after being reflected?
The focus of a concave mirror is the point on its optical axis where light rays parallel to the axis converge after being reflected.

Can chord is used to find the direction of reflected ray on a concave mirror if rays are parallel to principal axis?
no
Rays of light incident on lens and parallel to the principal axis of the lens converge?
This depends on the type of lens. If it is a convex lens then they converge at the focus on the other side of the lens. If it is a concave lens, then they diverge and appear to be coming from the focus present on the same side of the lens as the incident ray.
A ray of light traveling parallel to the principal axis of a concave mirror will be reflected out through the mirror's?
focus
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 does concave lenses do to light rays?
a concave lens diverges the light ray travelling in a straight parallel path.
What Rays traveling parellel to the principal axis of a concave mirror will reflect out through the mirrors focus?
Any ray that travels parallel to the principal axis of a concave mirror will reflect through the mirror's focus after reflection. This is known as the "law of reflection" for concave mirrors.
What is An incident ray that passes through the focal point of a lens?
An incident ray that passes through the focal point of a lens will emerge parallel to the principal axis. This is a property of convex lenses.
