At the Earth's orbital distance,the intensity of the solar radiation is approximately 1400 W/m².What is the value for the rms Electric field strength in solar radiation? A) 726 V/m B) 363 kV/m C) 527 kV/m D) 513 kV/m

Question

Quizplus · Accepted Answer

The intensity of solar radiation (I) is related to the rms 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 = 1400 W/m² gives approximately 726 V/m.
