    Answer:

    The amplitude of the oscillating electric field is 1316.96 N/C

    Explanation:

    Given;

    frequency of the wave, f = 2.4 Hz

    intensity of the wave, I = 2300 W/m²

    Amplitude of oscillating magnetic field is given by;

    B_o = \sqrt{\frac{2\mu_o I}{c} }

    where;

    μ₀ is permeability of free space = 4π x 10⁻⁷ m/A

    I is intensity of wave

    c is speed of light = 3 x 10⁸ m/s

    B_o = \sqrt{\frac{2*4\pi *10^{-7}*2300}{3*10^8} } \\\\B_o = 4.3899 *10^{-6} \ T

    The amplitude of the oscillating electric field is given by;

    E₀ = cB₀

    E₀ = 3 x 10⁸ x 4.3899 x 10⁻⁶

    E₀ = 1316.96 N/C

    Therefore, the amplitude of the oscillating electric field is 1316.96 N/C
