    Answer:

    A meter is a standard metric unit that is used to measure length. This means that a meter is part of the metric system of measurement. Guitars, baseball bats, and yard sticks are examples of objects that are about one meter long. Meters are also used to measure distances in races, such as running and swimming.

    The biggest advantage of the same is that the wavelength of light does not changes with time, pressure, temperature, etc. Moreover, it can be easily reproducible due to the presence of krypton everywhere. Also, it increases accuracy in the measurement of lenght.

    hope it helps u....

    Thanks.....

    Answer:

    The metre is defined as the length of the path travelled by light in a vacuum in 1299 792 458 of a second.
