In your lab, you are doing an experiment using a laser with intensity of $450\frac{W}{m^2}.$ What is the rms value of the electric field of this laser beam? $($The permittivity of free space $lo{n}_0=8\mathrm{.}85{10}^{-12}\frac{C^2}{N}*m^2$ and the permeability of free space ${}_0=4{10}^{-7}\frac{N}{A^2}.).$ Note: $E_{rms}=\frac{E_{\text{p}\text{e}\text{a}\text{k}}}{\sqrt[\phantom{2}]{2}}$

$4\mathrm{.}1\backslash$times $10$ EO $2\frac{V}{m}$
