The electric field \( E \) associated with a progressive electromagnetic wave is given by \( E = E_0 \sin(kx - \omega t) \). If \( B_0 \) is the amplitude of the magnetic field associated with the wave, then
- A \( \frac{E_0}{B_0} = \frac{\omega}{k} \)
- B \( \frac{E_0}{B_0} = \frac{\omega^2}{k^2} \)
- C \( \frac{E_0}{B_0} = \frac{k}{\omega} \)
- D \( \frac{E_0}{B_0} = \frac{k^2}{\omega^2} \)
Answer & Solution
Correct Answer
(A) \( \frac{E_0}{B_0} = \frac{\omega}{k} \)
Step-by-step Solution
Detailed explanation
\( \frac{E_0}{B_0} = c \) \( c = \frac{\omega}{k} \) \( \frac{E_0}{B_0} = \frac{\omega}{k} \)
