Planck's Constant (h) = Energy(E) / frequency (ν). Putting these domensional value valuesof Eand v in above equation we get, Dimensional Formula of Planck's constant = M1L2T-1. SI unit of Planck's constant is joule-seconds

Wavelength can be calculated using the following formula: wavelength = wave velocity/frequency. Wavelength usually is expressed in units of meters. The symbol for wavelength is the Greek lambda λ, so λ = v/f

Dear stuent 
For frequency calculation.
E = hf.
Here, E is the energy of each packet (or 'quanta') of light, measured in Joules; f is the frequency of light, measured in hertz; and h is of course Planck's constant.
Good Luck
