A Sinusoidal Electromagnetic Wave Has a Peak Electric Field Of 8.00

question 53

Multiple Choice

A sinusoidal electromagnetic wave has a peak electric field of $8.00 \mathrm { kV } / \mathrm { m }$ . What is the intensity of the wave? $\left( c = 3.0 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } , \mu _ { 0 } = 4 \pi \times 10 ^ { - 7 } \mathrm {~T} \cdot \mathrm { m } / \mathrm { A } , \varepsilon _ { 0 } = 8.85 \times 10 ^ { - 12 } \mathrm { C } ^ { 2 } / \mathrm { N } \cdot \mathrm { m } ^ { 2 } \right)$

• A) \(170 \mathrm {~kW} / \mathrm { m } ^ { 2 }\)
• B) \(11 \mathrm {~kW} / \mathrm { m } ^ { 2 }\)
• C) \(85 \mathrm {~kW} / \mathrm { m } ^ { 2 }\)
• D) \(21 \mathrm {~kW} / \mathrm { m } ^ { 2 }\)
