Length is a physical quantity that measures the extent of something along a straight line. Common units used to measure length include meters, centimeters, inches, and feet. Length is commonly used to describe the size and distance of objects.
Yes, as a convex lens becomes more curved, its focal length decreases. This is because a more curved lens causes light rays to converge at a point closer to the lens, resulting in a shorter focal length.
The line passing through the center of the lens perpendicular to its curved surfaces is called the principal axis. This axis is used as a reference point for measuring distances and angles in optics. It helps determine the focal point and focal length of the lens.
It is impossible to measure the length of a ray, because a ray is a line with one stopping point, and one never ending point. You can measure the angle between two connected rays though. Source(s): I'm an expert at Math and Science.
A graduated cylinder, measuring cup, or beaker can be used to measure liquid volume accurately. It is important to use the correct measuring tool and ensure the meniscus (the curved surface of the liquid) is at the correct measurement line for accuracy.
first we will put the divider in the starting of line then we will make points than we can measure it.

You can measure a curved line on a map by using a string or measuring tape to match the curve and then measuring the length against a ruler or a map scale. Alternatively, you can break down the curve into smaller straight line segments and then add up their lengths to get an estimate.
An arc length is the measure of the distance along the curved line making up the arc. It is longer than the straight line distance between the two end points.
Use a thread to measure the length of curved line AB. Put a knot on the thread near one of its end. Place this knot on on point A. Now, place a small portion of thread along the line, keeping it taut using your fingers and thumbs. Hold the thread at this end point with one hand. Using other hand, stretch a little more portion of the thread along the curved line. Go on repeating this process till the other end B of the curved line is reached
Length of any curve is imagined as an infinite sum of the lengths of infinitely small straight sections. If you look at a part of circle under a microscope you cannot tell that it is curved. This idea is used extensively in the branch of mathematics call "integral calculus". On a practical level, you can lay out a circle with a length of wire, then straighten it out to measure its length.
a line.
Put a string over the curved line. Measure the string. If you want to do it by calculations for some known function, use integration. Divide the curved line into many small pieces, so that each piece can be approximated by a straight line, and use Pythagoras' Formula for each piece: length = square root of (width2 + height2), using the width and height of the piece. In calculus books, you'll find methods that can get you an exact result in some cases.
It depends on what measure you want: the angle subtended or the length of the curved segment, and also on what information you do have.
A caliper or a micrometer is typically used to measure curved lines in a laboratory setting. These instruments provide precise measurements of the length or diameter of curved objects such as tubes or spherical surfaces.
A line does not have a definite length .It extends to infinity.Whereas a line segment has a definite measure.
