Final answer:
Option D). Sound waves from the radio station are transformed into electrical impulses that are sent over radio waves, then decoded by your radio and converted back into sound.
Step-by-step explanation:
Electrical impulses are created when sound waves are played by the radio station's D.J. These impulses are then encoded and sent via radio waves that fall within a certain radio frequency range. These radio waves are picked up by your car's radio, which decodes them and transforms them back into sound waves that play through the speakers. Electromagnetic waves, or radio waves, are used to transmit communications signals like AM and FM by altering their phase, frequency, or amplitude. This guarantees crystal-clear delivery of the delightful music or information to your ears.
