Question

In a plane electromagnetic wave propagating in
space has an electric field of amplitude 9 × 10³ V/
m, then the amplitude of the magnetic field is
(a) 2.7 × 10¹² T (b) 9.0 × 10⁻³ T
(c) 3.0 × 10⁻⁴ T (d) 3.0 × 10⁻⁵ T

Answer 1

Answer: option d.. is correct

Explanation:

Answer 2

Answer: option d

Explanation:

E = B×C

So , B= E/C where C is speed of light in vacuum , E is electric field , B is magnetic field.
