Question

If the magnetic field of a plane electromagnetic wave is given by (The speed of light

= 3 \times {10}^{8}m / s

)

B = 100 \times {10}^{- 6}sin

\left[2\pi \times 2 \times {10}^{15}

\left(t - \dfrac{x}{c}\right)\right]

then the maximum electric field associated with it is:

Correct answer: A. 3 × 10 ^ 4 N C ^ - 1

We know that relation between electric field E and magnetic field B is given by: (E)/(B) = c ⇒ E = Bc = 100 × 10 ^ - 6 × 3 × 10 ^ 8 V m ^ - 1 = 3 × 10 ^ 4 V m ^ - 1
