Question

which of the following is the planck's constant?​

Answer 1

Answer:

Planck's constant = 6.626 × 10^-34 m^2 kg / s

Planck's constant is defined as A fundamental constant, equal to the energy of a quantum of electromagnetic radiation divided by its frequency. S.I unit of planck's constant is joule second. ... Planck's constant is also used in uncertainty principle, in the relation of position and momentum.

E=hf

where, E = energy

            h = planck's constant

             f = frequency
