For electromagnetic radiation of intensity of 1.00 W/m²,what is the rms value of the electric field? A) 19.4 V/m B) 9.69 V/m C) 6.45 $\times$ 10^-8 V/m D) 9.11 $\times$ 10^-8 V/m E) 3.00 $\times$ 10⁷ V/m

Question

Quizplus · Accepted Answer

The intensity (I) of electromagnetic radiation is related to the rms value of the electric field (E_rms) by the equation I = (cε₀/2)E_rms², where c is the speed of light and ε₀ is the permittivity of free space. Solving for E_rms with I = 1.00 W/m² gives approximately 19.4 V/m.
