Question 4 Electromagnetism. At a location above the Earth's atmosphere, the maximum electne tield of the radiation contre Sun is 7.2 x 10 Calculate the interty of this radiation is af was party 385 x 102 cm A Moving to the next question prevents changes to this answer

Answer 1

Here we have given that,

E = 7.2 ×10^3 V/m

Here the formula for conversion into W/m² we have the relation as,

PFD = (V/m)²/377 watts per metre squared (W/m²)

So that here,

W/m² = (7.2×10³)²/377

= (137506.63129973476) Watts/m²

Which is our required answer.
