Answer:

B) They do not need a medium to transfer energy C) they transfer energy by disturbing electric and magnetic fields

Explanation:

I just took the test :)

B. They do not need a medium to transfer energy.

C. They transfer energy by disturbing electric and magnetic fields.

Electromagnetic waves:

  • Electromagnetic waves or EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field.
  • Electromagnetic waves are emitted by electrically charged particles and these waves can subsequently interact with other charged particles, exerting force on them.
  • The waves are created due to periodic change of electric or magnetic field
  • They do not need a medium to transfer energy.
  • They transfer energy by disturbing electric and magnetic fields.

Therefore, option B and C are correct.
