Question

what happens when electromagnetic waves cause a disturbance in electric and magnetic fields?
a. any particles in the fields move with them.
b. the fields line up parallel to each other.
c. they cancel vibrations in electric and magnetic fields.
d. the electromagnetic waves transfer energy.

Explanation:

Electromagnetic waves are disturbances in electric and magnetic fields. They transfer energy through these fields. Particles in the fields don't move with the waves (A is wrong). Electric and magnetic fields in electromagnetic waves are perpendicular, not parallel (B is wrong). They don't cancel vibrations but are the vibrations themselves (C is wrong).

Answer:

D. The electromagnetic waves transfer energy.
