A monochromatic plane electric-field-wave has a peak value 20 V/m. What is the peak value of the Magnetic field?

The peak value of the Magnetic field is 6.67 x 10⁻⁸ T

Explanation:

Given;

peak value of the electric-field, E₀ = 20 V/m

The peak of the magnetic field, B₀ = ?

The peak value of the magnetic field is given by;

B₀ = E₀/C

Where;

C is the speed of light = 3 x 10⁸ m/s

Substitute the givens and solve for B₀

B₀ = E₀ / C

B₀ = (20) / (3 x 10⁸)

B₀ = 6.67 x 10⁻⁸ T

Therefore, the peak value of the Magnetic field is 6.67 x 10⁻⁸ T

B₀ =

the answer is 12 as i may remember
