Photon Momentum

Momentum of a photon,

\(\Delta\,p=\cfrac{2}{c}\int ^{ x_{z} }_{ 0 }{ \psi } d\, x\)

Is \(a_\psi=x_z\)?  What does it mean when,

\(2πx=i.nλ\)

as \(\psi\) oscillates at \(f=\cfrac{c}{\lambda}\),

and the variation of \(\psi\) around a particle given by,

\(\psi=-i{ 2{ mc^{ 2 } } }\,ln(cosh(\cfrac { G }{ \sqrt { 2{ mc^{ 2 } } }  }(x-x_z)))+c\)

\(c=i{ 2{ mc^{ 2 } } }\,ln(cosh(\cfrac { G }{ \sqrt { 2{ mc^{ 2 } } }  }x_z))\)

both of which is from the same wave equation,

\(\cfrac{\partial^2\psi}{\partial\,t^2_c}=ic\cfrac{\partial^2\psi}{\partial\,x\partial\,t_c}\)

where one space dimension has been replaced with a time dimension.

\(a_\psi\ne x_z\).  Instead, in a 2D view, \(\psi\) shape like a torus of radius \(a_\psi\) and has extend from \(a_\psi-x_z\) to \(a_\psi+x_z\), the maximum energy density occurs on the perimeter of the circle with radius \(a_\psi\).


In which case we have a bound on \(x_z\),

\(x_z\le a_\psi\)

And,

\(\Delta\,p\le\cfrac{2}{c}\int ^{ a_{\psi} }_{ 0 }{ \psi } d\, x\) --- (*)

The other restriction on \(x_z\) is,

\(m_{ \rho \, p }c^{ 2 }=m_{ \rho  }c^{ 2 }-\int _{ 0 }^{ 2x_{ z} }{ \psi  } dx=m_{ \rho  }c^{ 2 }-2\int _{ 0 }^{ x_{ z} }{ \psi  } dx\ge0\)

So,

\(\Delta\,p\le m_{ \rho  }c\)

as we set \(x_z=a_{\psi}\) and substitute into (*).  \(m_{ \rho  }\) is the mass density of the particle fully expressed as mass.
