Find the dimensions of Planck’s constant h from the equation
E = hv where E is the energy and v is the frequency.
Energy of a radiation in terms of its frequency is given as
Energy(E) = Planck’s constant (h) × frequency(ν)
From the above relation 
Dimensions of E = [ML2T-2]
Dimensions of ν = [T-1]
Dimensions of h = 
.
