Final answer:
The amplitude of the magnetic field intensity (H0) and the amplitude of the electric field (E0) in an electromagnetic wave are related by the equation H0 = E0 / c.
Step-by-step explanation:
In an electromagnetic wave, the amplitude of the magnetic field intensity (H0) and the amplitude of the electric field (E0) at a point in space are related by the equation:
H0 = E0 / c
This equation represents the relationship between the amplitudes of the magnetic and electric fields in an electromagnetic wave. Here, c represents the speed of light in a vacuum, which is a constant value.
For example, if the amplitude of the electric field is E0 = 2 units, then the amplitude of the magnetic field would be H0 = 2 / c units.
The specific units would depend on the given units for the electric field.
So therefore in the Em wave, the amplitude of the magnetic field intensity (H0) and the amplitude of the electric field (E0) in an electromagnetic wave are related by the equation H0 = E0 / c.
