Question

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

Explanation:

Electromagnetic waves are a form of energy - carrying waves. When they cause a disturbance in electric and magnetic fields, they transfer energy. Electric and magnetic fields in an electromagnetic wave are perpendicular, not parallel (so A is wrong). They don't cancel vibrations but are the result of vibrating charges, and B is incorrect. While charged particles can be affected by electromagnetic fields, the main characteristic is energy transfer rather than just particle movement (C is not the best answer).

Answer:

D. The electromagnetic waves transfer energy.
