Focal length in a lens is the distance between the lens' optical center and the image sensor when the lens is focused at infinity. It determines the angle of view and magnification of the lens, with longer focal lengths resulting in a narrower angle of view and higher magnification, and vice versa. Focal length is commonly measured in millimeters.

What is the lens focal length formula used to calculate the focal length of a camera lens?
The lens focal length formula used to calculate the focal length of a camera lens is: Focal Length (Distance between lens and image sensor) / (1 (Distance between lens and object) / (Distance between lens and object))
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.
Does a diverging lens have a focal length?
Yes, a diverging lens does have a focal length. The focal length of a diverging lens is negative, as the light rays diverge after passing through the lens.
The distance from lens to focal point is called?
The distance from a lens to the focal point is called the focal length.
What will happen to the focal length of a lens if it is cut into half vertically?
When the lens is cut vertically then the focal length of the lens will increase.the focal length will become approx double.
What is the lens focal length formula used to calculate the focal length of a camera lens?

The distance from lens to focal point is called?
The distance from a lens to the focal point is called the focal length.
Explain how the focal length changes as a convex lens becomes flatter?
The focal length of a lens is the distance from the center of the lens to the point at which it focuses light rays. The bigger the focal length, the more powerful the lens. ChaCha!
Does the focal lens length have three classifications?
yes, focal lens length has three classifications
What will happen to the focal length of a lens if it is cut into half vertically?
When the lens is cut vertically then the focal length of the lens will increase.the focal length will become approx double.
Which lens has a greater power convex lens of focal length 10 cm or a convex lens of focal length 20cm?
Power is inversely related to the focal length. So convex lens of focal length 20 cm has less power compared to that having focal length 10 cm
How can one determine the focal length of a lens?
The focal length of a lens can be determined by measuring the distance between the lens and the point where light rays converge to form a sharp image. This distance is the focal length of the lens.
What is defined as the distance between a lens and its focal point?
focal length of the lens
Why focal length of convex lens is easier to find than a concave lense?
The focal length of a convex lens is easier to find than a concave lens because for a convex lens, the focal length is positive and is measured from the lens to the focal point. In contrast, for a concave lens, the focal length is negative and the rays of light are diverged. This makes it more challenging to find the focal point accurately.
What is the focal length of the convex lens?
The distance from the centre of the lens to the focal point.
