The main principle of a lens is to refract (bend) light waves in a way that converges or diverges them to create an image. This refraction occurs due to the change in density as light passes through the lens, causing the light rays to bend and focus at a specific point, allowing for magnification or reduction of objects.

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?
When rays of light incident on a lens and parallel to the principal axis converge, they meet at the focal point of the lens. This is known as focal point convergence, where the parallel rays are focused by the lens to a point on the principal axis.
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.
What happens when rays of light incident on a lens and parallel to the principal axis of the lens converge?
When rays of light incident on a lens and parallel to the principal axis converge, they meet at the focal point of the lens. This is known as focal point convergence, where the parallel rays are focused by the lens to a point on the principal axis.
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.
Length of a lens is the distance from the center of the lens to its principal focus?
That is incorrect. The length of a lens, or focal length, is the distance from the lens to its principal focus.
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 say main dish in spanish?
main in spanish is "principal"
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?
When light rays parallel to the principal axis of a lens converge, they will converge at the focal point of the lens. This is a property of converging lenses, where parallel rays are refracted and brought together at a single point. This focal point is where the image of a distant object will be formed by the lens.
What principal form of energy received by a digital camera through its lens?
Electromagnetic energy
