A red LED emits light at \( 0.1 \) watt uniformly around it. The amplitude of the electric field of the light at a distance of \( 1 \mathrm{~m} \) from the diode is:
(A) \( 5.48 \mathrm{~V} / \mathrm{m} \)
(B) \( 7.75 \mathrm{~V} / \mathrm{m} \)
(C) \( 1.73 \mathrm{~V} / \mathrm{m} \)
(D) \( 2.45 \mathrm{~V} / \mathrm{m} \)
\( \mathrm{P} \)
