An 800-MW Laser Beam Emits a Cylindrical Beam of Single-Wavelength Sinusoidal

question 22

Multiple Choice

An 8.00-mW laser beam emits a cylindrical beam of single-wavelength sinusoidal light $0.600 \mathrm {~mm}$ in diameter. What is the maximum value of the magnetic field in the laser beam? $\left( \varepsilon _ { 0 } = 8.85 \times \right.$ $\left. 10 ^ { - 12 } \mathrm { C } ^ { 2 } / \mathrm { N } \cdot \mathrm { m } ^ { 2 } , \mu _ { 0 } = 4 \pi \times 10 ^ { - 7 } \mathrm {~T} \cdot \mathrm { m } / \mathrm { A } , c = 3.0 \times 10 ^ { 8 } \mathrm {~m} / \mathrm { s } \right)$

• A) \(20.5 \mu \mathrm { T }\)
• B) \(17.2 \mu \mathrm { T }\)
• C) \(15.4 \mu \mathrm { T }\)
• D) \(12.4 \mu \mathrm { T }\)
• E) \(9.24 \mu T\)
