Radiation of a Single Frequency Reaches the Upper Atmosphere of the Earth

question 41

Multiple Choice

Radiation of a single frequency reaches the upper atmosphere of the earth with an intensity of $1350 \mathrm {~W} / \mathrm { m } ^ { 2 }$ . What is the maximum value of the electric field associated with this radiation? $( c =$ $3.00 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } , \mu _ { 0 } = 4 \pi \times 10 ^ { - 7 } \mathrm {~T} \cdot \mathrm { m } / \mathrm { A } , \varepsilon _ { 0 } = 8.85 \times 10 ^ { - 12 } \mathrm { C } ^ { 2 } / \mathrm { N } \cdot \mathrm { m } ^ { 2 }$ )

• A) \(1400 \mathrm {~V} / \mathrm { m }\)
• B) \(675.0 \mathrm {~V} / \mathrm { m }\)
• C) \(1350 \mathrm {~V} / \mathrm { m }\)
• D) \(1604 \mathrm {~V} / \mathrm { m }\)
• E) \(1010 \mathrm {~V} / \mathrm { m }\)
