    Answer:

    the rms value of the electric field component transmitted is 3.295 V/m

    Explanation:

    Given;

    intensity of the unpolarized light, I = 0.0288 W/m²

    For unpolarized light, the relationship between the amplitude electric field and intensity is given as;

    E_{max} = \sqrt{2\mu_0cI} \\\\E_{max} = \sqrt{2(4\pi \times 10^{-7})(3\times 10^8)(0.0288)} \\\\E_{max} = 4.66 \ V/m

    The relationship between the rms value of the electric field and the amplitude electric field is given as;

    E_{rms} = \frac{E_0}{\sqrt{2} } =\frac{E_{max}}{\sqrt{2} } \\\\E_{rms} = \frac{4.66}{\sqrt{2} }\\\\E_{rms} = 3.295 \ V/m

    Therefore, the rms value of the electric field component transmitted is 3.295 V/m
