Question

How do magnitude of electric and magnetic field affects the propagation of the electromagnetic wave​

Answer 1

Answer:

Explanation:

But in an EM wave, the electric field and magnetic field carry the same energy. So in an EM wave, the magnitude of the electric field is proportional to the magnitude of the magnetic field, and the proportionality constant is c, the speed of light!

Electromagnetic Wave: Electromagnetic waves are a self-propagating transverse wave of oscillating electric and magnetic fields. ... This means that an electric field that oscillates as a function of time will produce a magnetic field, and a magnetic field that changes as a function of time will produce an electric field.

According to photon, they can not be affected by electric and magnetic fields. But EM waves are affected by external electric and magnetic fields.

Answer 2
