What is the pole of a lens?
The pole of a lens is the midpoint of the lens' geometric axis. It is where the principal axis intersects the lens.
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 happens when rays of light incident on a lens and parallel to the principal axis of the lens converge?
-- The distance from the center of the lens to the plane in which the rays converge is the 'focal length' of the lens. -- If the rays emanated from one point on an object, then rays from all the other points on the object do the same thing, and a real image is formed.
What is the center of curvature of a lens?
The center of curvature of a lens is the point located at a distance equal to the radius of curvature from the center of the lens. It is the point where the principal axis intersects the spherical surface of the lens.
Rays of light incident on a lens anb parallel to the principal axis of the lens converge?
When rays of light are incident parallel to the principal axis of a lens, the rays converge at the focal point after passing through the lens. This property is used in converging lenses to form real and inverted images at a specific focal distance from the lens.

The pole of a lens is the midpoint of the lens' geometric axis. It is where the principal axis intersects the lens.
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.
If a convex lens of focal length f splits into two equal parts what will be the new focal length?
there can be two ways to cut a convex lens into two equal parts-- one, along the principal axis and another, perpendicular to the principal axis. If the lens is cut along the principal axis, then there will bo NO change in the focal length of the lens. But, if it is cut perpendicular to the principal axis, then the focal length will be twice the original one.

Length of a lens is the distance from the center of the lens to its principal focus?
It is called the focal length. It is equal to 1/2 times r, and is positive on concave mirrors and negative on convex mirrors.
How do you say main dish in spanish?
main in spanish is "principal"
The blank length of lens is the distance from the center of the lens to its principle focus is what?
The blank you are referring to is the focal length of the lens. It is the distance from the center of the lens to its principal focus, where parallel rays of light converge after passing through the lens.
How do you draw a ray diagram for an object placed in front of a convex lens?
To draw a ray diagram for an object placed in front of a convex lens, first draw the principal axis and the lens. Then, draw three primary rays: one parallel to the principal axis that passes through the focal point on the other side of the lens, one passing through the center of the lens which continues straight, and one passing through the focal point on the same side of the lens which emerges parallel to the principal axis. The point where these three rays intersect will give the image location.
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.
What principal form of energy received by a digital camera through its lens?
Electromagnetic energy
