In an electromagnetic wave, at any instant the electric field was found to oscillate with an amplitude of

18\, \mathrm{v} / \mathrm{m}

. The magnitude of oscillating magnetic field will be -

View answer and explanation

Correct option: B

6 \times 10^{-8} \mathrm{~T}

Option B (

6 \times 10^{-8} \mathrm{~T}

) is correct because the magnitude of the oscillating magnetic field is calculated using the formula

B_0 = \frac{E_0}{c}

, where c is the speed of light.
