free electromagnetic field वाक्य

उदाहरण वाक्य

1. The idea of quantization of the free electromagnetic field was developed later, and eventually incorporated into what we now know as quantum field theory.
2. :: : Fair enough, there are no interactions for free particles, but the QED lagrangian also contains the terms for a free electromagnetic field, which wouldn't be covered by the Dirac equation.
3. As a consequence of the uncertainty principle, source-free electromagnetic fields, that are always present and have some intrinsic zero-point energy, exist in QED out of necessity in order for the theory to be mathematically consistent.
4. :: : : Or just consider that the photon is itself an excited state of the electromagnetic field, the field in the medium is, of course, described by the free field plus the interactions with the medium and quantizing that will lead to a different beast than quantizing the free electromagnetic field.
