In [1] the formula for the determination of the photon force was received:$\left| F \right|=\frac{hc}{\lambda ^2}$ (1). The pressure of the photon can be calculated according to the following formula [1]: $P=F \mathord{\left/ {\vphantom {F A}} \right. \kern-\nulldelimiterspace} A$ (2). In [2] the effective area of the photon was defined: $A=\pi \lambda ^2$ (3). By using the Eq. (1) together with Eq. (2) and (3) the following equation can be derived:$P=\frac{hc}{\pi \lambda ^4}$ or $P=const\cdot \lambda ^{-4}=6.323052{\kern 1pt}\;10^{-26}\cdot \lambda ^{-4}$ (Pa) (4). The thermodynamic analysis has shown that the equation -$P_h V_h =kT$ can be used by describing of the photon thermodynamic condition in such form $P_p V_p =hf$(5). The use of the Eq. (4) and (5) makes the calculation of the photon volume $V_p $ possible: $V_p ={hf} \mathord{\left/ {\vphantom {{hf} P}} \right. \kern-\nulldelimiterspace} P_p =\pi \lambda ^3$ (6). The new equations (5,6) were proved with one theoretical procedure: $-{{dE} \mathord{\left/ {\vphantom {{dE} {dt}}} \right. \kern-\nulldelimiterspace} {dt}=-d(PV)_p } \mathord{\left/ {\vphantom {{{dE} \mathord{\left/ {\vphantom {{dE} {dt}}} \right. \kern-\nulldelimiterspace} {dt}=-d(PV)_p } {dt}}} \right. \kern-\nulldelimiterspace} {dt}=hf^2$ (7). Finally, it is possible to calculate the density of the light particle: $V\rho =m=h \mathord{\left/ {\vphantom {h {c\lambda }}} \right. \kern-\nulldelimiterspace} {c\lambda }$ or $\rho =const\cdot \lambda ^{-4}=0.703534\;10^{-42}\cdot \lambda ^{-4}$ [kg/m$^{3 }$] (8). With the Eq. (4) and (8) one other pressure equitation can be expressed: $P=\rho c^2$ (9). The multiplying the left and right sides of this formula on V by using the Eq. (5) delivers the famous, well-known Einstein formula $E=mc^2$. \textbf{[1] }Determination of the Photon Force and Pressure. S.
