Question

Write the relation between the velocity of propagation and the magnitudes of electric and magnetic fields.

Answer 1

The relation between the velocity of propagation and the magnitudes of electric and magnetic fields is given by

`c=E/B`

Here,
c = Velocity of the electromagnetic wave
E = Magnitude of the electric field
B = Magnitude of the magnetic field

Note that electromagnetic waves propagate with the speed of light. So, in this case, c is the speed of light.
