Calculate the energy of quantum of radiant energy with a frequency of 5.00 x 10^11/s. this can be solved using Planck-Einstein Equation
 E = hf
 Also known as Planck's Relation, the energy of a photon is given by:
  
  , where:
  
 E = Energy (J)
  
 h = Planck's Constant (J*s) = 6.626070040×10−34 Js
  
 f = Frequency (Hz) = 5.00 x 10^11/s
  
 E= 3.31x10^-22 j
