A sinusоidаl electrоmаgnetic wаve is prоpagating in vacuum. At a given point P and at a particular time, the electric field is in the +x direction and the magnetic field is in the -y direction. If the intensity of the wave at point P is `p` W/m2, what is the rms electric field Erms at that point? (c = 3.00 × 108 m/s, μ0 = 4π × 10-7 T ∙ m/A, ε0 = 8.85 × 10-12 C2/N ∙ m2) Round your answer to 1 decimal place.
