Yes, Planck's constant is 6.63 x10^-34 Joule-second. Planck's constant is "h".
The speed of light is close to 3 x10^8 m/s. Divide speed of light by wavelength to get frequency.
Multiply frequency by Planck's constant to get energy. E=hf

We have energy equals to
E=hv ( where h is plancks constant having the value 6.626068 Ã 10^-34 m2 kg / s or Js and the v is 'nu' or the frequency which is 2Pi/wave length.)

E = hc/(wavelength), where h is Planck's constant and c is the speed of light.
