In an electromagnetic wave, the amplitude of magnetic field is \( 1.1 \times 10^{-6} \text{ T} \). What is the amplitude of electric field?
- A 3.70 N C\( ^{-1} \)
- B 37 N C\( ^{-1} \)
- C 330 N C\( ^{-1} \)
- D v3.30 N C\( ^{-1} \)
Answer & Solution
Correct Answer
(C) 330 N C\( ^{-1} \)
Step-by-step Solution
Detailed explanation
\( E_0 = c B_0 \) \( E_0 = (3 \times 10^8 \text{ m/s}) \times (1.1 \times 10^{-6} \text{ T}) \) \( E_0 = 330 \text{ N C}^{-1} \)
