Standard length of a meter in 1983?
100cm
How was the length of a standard meter redefined in the year 1983?
It was redefined as 3 feet...
What terms was standard meters defined in on 1983?
Originally, a metre was defined as 1/10,000,000th of the distance from the Earth's equator to the North pole. Since 1983 it has been defined as:the length of the path travelled by light in a vacuum during a time interval of 1/299,792,458th of a second.
How was the length of a meter redefined in the year 1993?
It was not. The current definition was established in 1983.
How was the length of standard meter redefined?
The French were the first to define the length of a meter by using a alluminium/platinum alloy bar of a meter length at 25 degrees Celcius. This however is very inaccuracte for quantum measurements as the length of the bar would change two much depending on how you hold it. A better measurement found in 1983 is the distance that light travels in a vacuum in 1/229,792,458ths of a second. (for those of us with a decent knowledge of relativity that measurement is taken in the rest frame). Crazy I know but at least this way any body in a good physics lab can reproduce this distance without the use of some silly French rod.
What problems are there in maintaining and using a metal bar as the primary length standard as was done before the meter redefined in 1983?
Dimension change due to temperature fluctuation (expansion and contraction) would be one.
How can you tell what a millimeter is?
If you get hold of a ruler, it will have a millimeter scale on it so that you can measure a millimeter. A millimeter is a thousandth of a meter. A meter is a standard unit of length defined as the length as equal to the distance travelled by light in vacuum during a time interval of 1/299,792,458 of a second after the meeting of the seventeenth CGPM (General Conference on Weights and Measures) in October 1983.
What is the largest metric unit of length?
The meter, which is defined, as of 1983, as the length of the path traveled by light in a vacuum in an interval of 1/299792458 seconds. This is a Systeme Internationale standard measurement.
How was the lenght of a standard meter redefined in the year 1983?
they put thangs tew gether nd they brainstormed alot.
What are the three intermediate definitions of the meter between 1793 and 1983?
The meter was defined in 1792 as 1/10,000,000 of the distance between the North Pole and the equator on a line running through Paris, France. The standard length of a meter was later changed to be the distance between two fine lines engraved on a bar of platinum and iridium alloy. The next definition was based on the wavelength of light emitted by an isotope of the element krypton. The present definition, in use since 1983, is the distance light travels in a vacuum during approximately one three hundred millionths of a second (1/299,792,458 sec).
How was the length of a meter created?
The meter was defined by the French Academy of Sciences as the length between two marks on a platinum-iridium bar, which was designed to represent one ten-millionth of the distance from the Equator to the North Pole through Paris.In 1983, the meter was redefined as the distance traveled by light in free space in 1⁄299,792,458 of a second.
