Ann and Jesse’s mom is driving them to school. They are listening to music on an FM radio station. When they ride in the car with their father, they sometimes listen to AM radio. Ann wants to find out the difference between AM and FM radio signals. She finds a diagram in an online search. How do the AM and FM radio waves compare? In your answer, explain how the wavelength affects the frequency of the radio waves.
the difference is that the carrier waves are altered. am waves amplitude (strength) is varied in the signal to get sound information. Fm waves frequency’s are varied based on the carrier signal.
