Answer :
Answer:
[tex]3.33\cdot 10^{-8} T[/tex]
Explanation:
For an electromagnetic wave, the relationship between magnetic field amplitude and electric field amplitude is given by
[tex]E=cB[/tex]
where
E is the amplitude of the electric field
c is the speed of light
B is the amplitude of the magnetic field
For the electromagnetic wave in this problem, we have
E = 10 V/m is the amplitude of the electric field
So if we solve the formula for B, we find the amplitude of the magnetic field:
[tex]B=\frac{E}{c}=\frac{10 V/m}{3\cdot 10^8 m/s}=3.33\cdot 10^{-8} T[/tex]
