How does one derive the Planck-Einstein relation (E= hf) from the total energy (H) equation and from the Schrödinger equation?
P.E. indicates potential energy, and K.E. indicates kinetic energy. And H indicates the Hamiltonian…
Hopefully, we can produce an affirmative answer to our question soon. And that question is a good start in our quest to advance the theory of energy.
Good luck! 🙂
Hints: Think massless or almost massless photons. Think Lagrangian which is defined as Kinetic Energy (K.E.) – Potential Energy (P.E.) And finally, think the theory of relativity.
Remark: Gravity (spacetime) is quantized! Amen! 🙂
