Energy of waves such electromagnetic waves is given by E=hf=p c=h c\l

Where h is Planck constant,c is light speed which is constant and l is the wave length.,so E=const.\l, therefore measuring l gives the energy E.or measuring the frequency gives the energy E.

Where energy of moving particle is E=1\2 mv^2 ,so knowing the mass m in kg,and the velocity v ,E can be found,

So,they have different ways of measuring the energy they carry.
