Question

Write the relation for speed of electronmagnetic waves in terms of the amplitude of electric and magnetic fields

Answer 1

Electromagnetic waves are transverse in nature where electric and magnetic fields are perpendicular to each other and to the direction of wave propagation. They are not deflected by electric and magnetic fields, hence the relation for its speed in terms of amplitudes of electric and magnetic fields will result as,

                 E₀ = cB₀ (or) c = E₀/B₀
