As you know, energy is defined as frequency multiplied by Planck's constant.
Energy is also defined as mass multiplied by the square of the speed of
light.
E=hf and E=mc^2
If we set hf equal to mc^2,
hf=mc^2
We can focus on mass, by moving c^2 to the other side,
m=(hf)/(c^2)
And combine the two constants into a single constant, known as the
Westmoreland Constant,
y=h/(c^2)
Now mass equals frequency multiplied by the Westmoreland constant.
m=yf
The particle fields in the new atom model retain a particular resonance
frequency. When photons are absorbed or emitted, it changes the resonance
frequency, causing the atom to have a higher energy state.
