Photon energy is proportional to angular frequency ================================================== Photon is the elementary part of any electromagnetical radiation, having no mass and moving with speed of light in any reference frame. The energy of a photon depends only on its frequency. **Notation:** #. :math:`\hbar` (:code:`hbar`) is :attr:`~symplyphysics.quantities.hbar`. **Links:** #. `Wikipedia `__. .. py:currentmodule:: symplyphysics.laws.waves.photon_energy_is_proportional_to_angular_frequency .. py:data:: energy :attr:`~symplyphysics.symbols.basic.energy` of a photon.
