The
kilogram redefined is " JUST A BUNDLE OF ENERGY"
While the ampere, kelvin and mole will be tied to the elementary
electrical charge, the Boltzmann constant and the Avogadro
constant, respectively, the kilogram will now be defined by the
Planck Constant.
A physical constant
that is the quantum of action, which relates the energy in one
quantum (photon) of electromagnetic radiation to the frequency
of that radiation.
A photon's
energy is equal to the Planck constant times its frequency.
A physical constant
that is the quantum of action, which relates the energy carried by
a photon to its frequency. A photon's
energy is equal to the Planck constant times its frequency.
Which is to say, Planck's constant,
symbolized h, relates the energy in one quantum (photon) of
electromagnetic radiation to the frequency of that radiation. In
the International System of units (SI), the constant is
equal to approximately 6.626176 x 10-34 joule-seconds.
The equation reveals that mass can
be understood and even quantified in terms of energy.
Planck's equation shows that energy, in turn, can be calculated in
terms of the frequency ν of some entity such as a
photon (a particle of light), or alternatively, with some
mathematical substitutions, a mass- times a multiple of h.
The multiple must be a positive integer- such as 1, 2 or 3.
The integer aspect is what makes the relationship "quantised"
— matter releases energy in discrete chunks, known as
“quanta,”
which can be imagined as individual packets or bundles of energy.
Thus, the ultimate purpose of the
"Watt Balance" is
to help scientists generate a reliable calculation of
Planck's Constant. A universal value that quantifies the
relationship between energy, light and an object's mass,
which in turn will produce a new, more accurate basis
for defining the kilogram worldwide.
Just as the meter, once defined as the length of a bar of platinum, was
redefined in 1983 by a formula using the speed of light
as the distance light travels in a vacuum over
1/299,792,458 of a second.
Which means that the length
of a meter, like the kilogram will never change. |
