What phenomenon in nature do scientists use to define the length of a meter? Why is this a better definition than “the length of a standard meter stick”?
Answer from: berrydivina
The natural phenomenon used to describe the length of a meter is the speed of light. The length of a meter is the length a light path travels in 1/(299792458) seconds through a vacuum.
The definition is better due to the uncertainty involved in the use of the length of a standard meter stick because the length of the meter stick could change due to atmospheric conditions from place to place
