Answer:
d They are perpendicular (90º)
Step-by-step explanation:
When electric and magnetic fields moves they are perpendicular to one another.
- Electromagnetic fields are composed of both electric and magnetic fields.
- In motion, the two fields moves perpendicular to one another.
- These waves are mostly generated through natural activities.
- They are called transverse waves and moves perpendicular to the particles.
- Examples are light waves, radio waves, etc.
