Discrete wavelet structure and discrete energy of classical plane light waves

In this letter, the wavelet transform is used to decompose classical linearly polarized plane light wave into a series of discrete Morlet wavelets. It found that energy can be discrete, associated with its structure.It also changeable basic packet or train vector $\mathord{\buildrel{\lower3pt\hbox{$\scriptscriptstyle\rightharpoonup$}}\over k} $ and structure form ${H_{0k}} = n{p_{0k}}\omega$ $(n 1,2,3,...)$, where $n$ parameter structure, $\omega idler frequency train, ${p_{0k}}$ constant determined.This consistent division $P$ portions in Planck radiation theory, an integer. Finally, random packets $n=1$ are simulate Mach-Zehnder interference single photons, showing wave-particle duality light.
