Write the value and unit of Planck's constant.
(N/A) Planck's constant,denoted by $h$,is a fundamental physical constant that relates the energy of a photon to its frequency.
Its value is approximately $h = 6.626 \times 10^{-34} \ J \cdot s$.
The $SI$ unit of Planck's constant is Joule-second $(J \cdot s)$.
