The amplitude of the magnetic field of a harmonic electromagnetic wave in vacuum is \(B_0=610 nT\). The amplitude of the electric field of the wave is:
- A \(5 \times 10^{14} N C ^{-1}\)
- B \(203 \times 10^{-17} N C ^{-1}\)
- C \(183 N C ^{-1}\)
- D \(610 N C ^{-1}\)
Answer & Solution
Correct Answer
(C) \(183 N C ^{-1}\)
Step-by-step Solution
Detailed explanation
\(E_0 = c B_0\) \(E_0 = (3 \times 10^8 \text{ m/s}) \times (610 \times 10^{-9} \text{ T})\) \(E_0 = 183 \text{ N C}^{-1}\)
