An electromagnetic wave has an energy of $478$ joules and a frequency of $27$Ggatz. How long is the wave?

$478J={6\mathrm{.}626}^{-34}Js*r,E=478J$

$r=\frac{478}{6\mathrm{.}626-34s}=(\frac{478}{6\mathrm{.}626}){10}^{-34}{s}^{-1},h=6\mathrm{.}626{10}^{-34}Js$

$72\mathrm{.}14{10}^{-34}{s}^{-1},3{10}^8\frac{m}{s}=*72\mathrm{.}1418$

$=\frac{3{10}^8\frac{m}{s}}{72\mathrm{.}14{10}^{-34}{s}^{-1}}==(\frac{3}{72\mathrm{.}14}){10}^{8-34}m=$
