Answer:
the magnitude of the magnetic field of the wave is 16.7 nT
Explanation:
Given the data in the question;
Electric field E = 5.00 V/m
we know that the expression for the electric field of an electromagnetic wave in terms if magnetic field is;
E = cB
where c is the speed of light ( 3 × 10⁸ m/s )
and B is the magnetic field
so we solve for the magnetic field
B = E / c
we substitute in the value of E and c
B = (5.00 V/m) / (3 × 10⁸ m/s)
B = 1.67 × 10⁻⁸ T
B = 1.67 × 10⁻⁸ T
B = 16.7 nT
Therefore, the magnitude of the magnetic field of the wave is 16.7 nT
