An electromagnetic wave with a peak magnetic field component of 1.68 × 10−⁷ T has an associated peak electric field component of what value? (μ₀ = 4π × 10−⁷ T⋅m/A,ε₀ = 8.85 × 10−¹² C²/N⋅m² and c = 3.00 × 10⁸ m/s)

Question

Quizplus · Accepted Answer

The peak electric field (E) can be calculated using the relation E = cB, where c is the speed of light and B is the peak magnetic field. Substituting the given values, E = (3.00 × 10^8 m/s)(1.68 × 10^-7 T) = 50.4 N/C.
