"Graduated" measuring instruments (graduated pipette, ruler) are divided into "grades".
They have something called atomic fingerprints.

The series of lines in an emission spectrum caused by electrons falling from energy level 2 or higher (n=2 or more) back down to energy level 1 (n=1) is called the Lyman series. These emission lines are in the ultra-violet region of the spectrum.
The Lyman series is scientifically defined as the series of transitioning of hydrogen atom spectral lines that are found within emission lines of ultra violet.
Spectroscopy originated through the study of visible light dispersed by a prism according to its wavelength. An instrument called a spectrometer is used in spectroscopy for producing spectral lines and measuring their wavelengths and intensities.
At first they will use the twine to measure the curved lines and then they will take one scale and looke the measure
the simplest way to measure the curved lines is by using a thread...........or cloth type tape
Such a device is known as a protractor.
a tool used to draw straight lines or measure straight lines miss pawz: a measuring instrument :)
The instrument that is used to construct straight lines is called a rule. Often people make the mistake of calling it a ruler, but its a rule.
"A ruler, sometimes called a rule or line gauge, is an instrument used in geometry, technical drawing, printing and engineering/building to measure distances and/or to rule straight lines. Strictly speaking, the ruler is essentially a straightedge used to rule lines[citation needed], but typically the ruler also contains calibrated lines to measure distances"
The lines parallel to the equator are referred to as Lines of Latitude and are used to measure degrees above and below the equator. They are also called parallels and include the Arctic and Antarctic Circles and the Tropics of Cancer and Capricorn; the equator is the longest line of latitude on the earthSee the link below
The "lines" are called latitude lines.lines of latitude
Lines added to the stave when notes are below or above the top of the stave are called "ledger lines" or "leger lines". They can occur in any stave indicating an instrument with melody.
It's called a measure.
It's called a measure.
the answer is longitude and latitude lines
