Dear student
 
The Planck’s constant (h) can be defined as a proportionality constant that relates the energy (E) of a photon to the frequency (ν) of its associated electromagnetic wave.Mathematically,Planck’s Constant (h) = Energy(E) / frequency (ν).Dimensional Formula of energy = M1L2T-2.Dimensional Formula of frequency = M0L0T-1.Putting these values in above equation we get,Dimensional Formula of Planck’s constant = M1L2T-1.SI unit of Planck’s constant is joule-seconds (j-s).  RegardsArun (askIITians forum expert)

As the formula of planks constant ,h is h =E/v.That is energy /frequency.The dimension of planks constant is ML^2T^-1.
