Question

For an EM wave propagating along x direction , the magnetic field oscillates along the z direction at a frequency of 3×10(10) Hz and has amplitude of 10×(-9)T. Write the expression representing the corresponding electric field​

Answer 1

Answer0.3

Explanation:

E=BC

10×(-9)×3×10^8=0.3

Answer 2

The corresponding electric field​ is 0.3 V/m.

Explanation:

The amplitude of magnetic field, $B=10^{-9}\ T$

The magnetic field oscillates along the z direction at a frequency of, $f=3\times 10^{10}\ Hz$

It is required to find the expression representing the corresponding electric field​. The relation between the electric and magnetic field is given by :

$E=Bc$

c is speed of light

$E=10^{-9}\times 3\times 10^8\\\\E=0.3\ V/m$

So, the corresponding electric field​ is 0.3 V/m.
