Final answer:
The electric field and magnetic field of an electromagnetic wave are in phase, perpendicular to each other, and related to the speed of light.
Step-by-step explanation:
The electric field (E) and magnetic field (B) of an electromagnetic wave are related in several specific ways:
- The E and B fields are in phase with each other, meaning that their peaks and troughs coincide.
- The E and B fields are perpendicular to each other as well as to the direction of propagation of the wave.
- The ratio of the electric field to the magnetic field amplitude is given by E/B = speed of light (c).
Therefore, when discussing an electromagnetic wave, all of the statements provided (being in phase with each other, being perpendicular, and being related to the speed of light) are correct.
